There are many phones with a headphone jack that have an IP68 rating which invalidates your whole point. If the headphone jack was so compromising then Apple would have needed to remove the charging port as well.
A sick and twisted part of me wants to see charging ports removed too. Every port! Make it IP69+ compliant. Maybe then the careless kids I know might keep a device alive for more than a year. Ultimately all that would do is barely solve one problem and introduce a whole lot of other problems.
