"I’m also concerned that an SFW version could end up cutting a lot of content"
That's definitely more of a writing issue than the actual NSFW option. I would've specified which person has done a good example of that but since this game is like really popular i don't want minors to go check that game out, but it's definitely very possible since it shouldn't really have more dialogue than NSFW related things.
Either way it's a suggestion and at the end of the day whatever the option may be (paywall, NSFW paywall or completely free) those are all valid.
