This.I do, however, believe it is necessary to get general player buy in. "This adventure has strong body horror elements that may well affect PCs. If we are going to run this, everyone has to be in for that possibility." Maybe "buy in" counts as consent.
Back in Session 0 we'd discuss things that are likely to be an issue. If any player isn't happy with that, we play something else. Which is absolutely fine with me.
But a player at my table doesn't get to individually opt out of something like that - it's either on the table for all the PCs, or none.
(And, yes, there's the possibility that something that wasn't expected to cause an issue suddenly turns into one. If that ever does happen, I'll let you know how it goes.)
