The 2017 model pictured in this post supported Thunderbolt 3, which was a 40 gbps connection. Supported display modes included up to 4k@120, 2x4k@60, or 5k@60, which was better than the then-standard HDMI 2.0.
What combination of resolution, frame rate, and color depth are you envisioning that having a dock handle a gigabit Ethernet connection, analog audio would require scaling down the display resolution through the same port?
Even if we talk about DisplayPort Alt Mode, a VESA standard developed in 2014, and supported in the 2017 models pictured in this post, that’s just a standard DP connection, which in 2017 supported HDR 5k@60. But didn’t support a whole separate dock with networking and USB ports.

Right, for a single device.

Dual 4k120 would already saturate the bandwith. Regarding networking, gigabit is pretty slow for LAN depending on your workload. If you were to require 10gbit, you’d be SOL.
By 2021, the MacBook Pros were supporting TB4, and the spec sheets on third party docking stations were supporting 8k resolutions, even if Macs themselves only supported 6k, or up to 4x4k.
Did you read the specs in your link? Even with that TB4 dock you wouldn’t be able to do dual 4k120.
I really don’t get trying to justify manufacturers forcing you to buy an additional device to get the same ports they could provide natively without using a hub/dock. It’s a pretty submissive attitude.
What would you use to drive dual 4k/120 displays over a single cable, if not Thunderbolt over USB-C? And what 2017 laptops were capable of doing that?
Even if we’re talking about two different cables over two different ports, that’s still a pretty unusual use case that not a lot of laptops would’ve been capable of in 2017.
4k120 panels weren’t even available in 2017 afaik. But you could do dual 4k120 with one hdmi 2.1 and 1 displayport 1.4 so just need 2 video outputs from your laptop (which used to be pretty common).
Please note that we’re having this discussion in 2024 and I’m talkimg about use cases in 2024. I don’t really see the point in talking about what you would theoretically do 6 years ago with panels that weren’t even available.
Also, that’s the total bandwidth in a best case scenario. You’re not factoring in that you’ll need to share that with all of the devices in a hub. That’s without mentioning that you need the hub (which also has a cost).
The USB4 protocol can handle 160Gb/s split asymettrically (so, say, 120Gb/s out, 40Gb/s in), wheras the upper limit for DisplayPort’s highest bandwidth mode, Quad UHBR 20, is 80Gb/s in one direction. So you can saturate your DisplayPort 2.0 quad-channel with more than enough bandwidth to power three 10K 60Hz 30-bit (i.e. very high-end) monitors in DSC mode, and still only be using half the bandwidth of USB4, all using a single cable which I can also use to charge my earphones.
Uhm no? There are more than a few use cases that require a mobile set up for demos for example but that you’d also want to use in a desk setting. For example, architects or sw dev.
Which is still enough for almost all sane use cases.
Like 2 4k60 monitors and literally nothing else? You have a very conservative opinion of what a “sane” use case is. Not to mention that lots of USB-C cable certification is a mess so not even getting the cable is simple (or cheap).
Show me one architect that is actually dragging along two external 4k displays with their laptop.
If you are a professional with specific needs buy a specific laptop. Frankly there are more than enough laptops that have more ports if that’s what you need. Except even in your example you don’t even need more ports because you can just use the second USB4 port.
You misunderstood. They use those monitors when actually working in a stationary place with their desktop setup. However, it’s very common to then have to go to your client’s office to show them said work or discuss future steps. At which point having multiple port options comes in handy if you have to plug in to a tv, monitor or projector.
You can’t seriously consider asking for hdmi and displayport on a laptop a “specific need”.
You can only do that because your monitors are not high resolution and high refresh rate. The data cap for usb-c is not that high.
Can you break this down?

USB-C is just a connector, but Thunderbolt 5 uses it and for asymmetric uses (e.g. a monitor) it can hit 120Gbps.
Isn’t that going to support most monitors?
Please, list the devices that you know have tb5.

Almost every laptop does have a dedicated HDMI port
