Maybe I'm naive here but if the dev says it wont be there, I think it won't. Especially if they reconfirm this in this very thread. Not sure what your problem is or why their comment gets downvoted a bunch. Yes, it does seem to get teased. But you can tease it without delivering it.
Im honestly not 100% sure if characters getting raped would count as NTR or not. Possibly not. Getting raped is not cheating. But I still kinda hope MC will prevent that from happening. Maybe non-con will happen in the bad endings. Maybe it won't.
In all honesty, I don't care super much about what happens in the bad endings.
