Secondly, as BaiBai already said, the rework won't affect all the content and won't take that long (especially if he gets help from the community).
Yes, BaiBai did say it won't take too long. And he's lying to himself. By his own admission, he'd have to re-do every single render with the MC, as well as several other characters (Stephanie, Viktoria, Cathrine, Emily, and Lola), which accounts for a huge portion of the renders. Every scene in which any of those characters appears would have to be redone; that's going to take a very long time. I'd say that scenes in the game which don't include the MC, Stephanie, Viktoria, Cathrine, Emily or Lola in some capacity are less than 20% of the game, and I think that's a very generous estimate.
I think it's clear that he's intending to do that, and he's trying to convince himself that's not a big deal so as not to demoralise himself with the scale of the problem, rather than acknowledging that between re-renders, re-writes (huge chunks, everything related to family, which accounts for a lot of the content) and re-translation (a part of the process that already takes a lot of time), it's going to be probably at least a year, likely more, until he gets back to the point he's currently at.
He's said himself it would take time, I just don't think he's being realistic about how much time.
If he goes the "official release is completely platonic relationships between family rmembers" route, he'd need to not include the "true" renders or text in the official release. The "unofficial fan patch" would have to add them, not merely unlock their availability. If he included them in the base release and there was a patch to unlock them, it'd only take one person telling Itch.io that was the case for him to be banned from the platform.
He absolutely should NOT rush a harem ending into version 0.10. That was an utterly ridiculous suggestion that guy made.
