I don't know if my opinion is tricky or something, but I do spark a key to fix problems about futa:
Add an extra note to explain such elements.
Overall, I believe that CBoyC95 has his/her reasons to include games. And I am grateful for him/her and I shall support as I always do since the 1st day I came to know this list
For lesbian-mained games with slight futa elements, a note may be added. And if it's OK, a rough description of concrete detail can be provided.
Like for MLS, an explaining note can be added:
"This game is definitely a lesbian game overall, but recently futa scenes are added. However, it's avoidable."
Hmmmmmm, that's what I have conceived. Don't know if it's gonna work, hope this might be helpful. I don't intend to "revert" the whole list because this is his/her list, and what I can offer is just an immature reference.
