People prefer to have a headphone jack over water-resistance?
It is pretty save to assume it's no longer water-resistance as it was coming from the factory after the drilling?

Also, it's not a real trade-off, as currently, everyone except Apple somehow manages to make a waterproof smartphone with a headphone jack.
Also plenty of people have have water damaged phones, from using them in bath, dropping then in the toilet or simply forgot to take them out of their pockets before plunging into the ocean. That you don't know these people or don't do it yourself, doesn't mean there are few water damaged phones.
