I’d say these days it’s essentially required. Common example: I had my phone in my pocket while headed to a pool party. Totally forget it was in my pocket and just got in the pool. Absolutely no problem, just pulled it out (after it was in the pool for minutes) and everything was fine. No panic. In comparison, I remember doing the same thing many years ago with a moto razr. Even after rice and drying and pulling the battery, it was toast. Had to get a new phone.
