FYI, the purpose of an "incest patch" isn't just to give players the option, but to bypass Patreon's strict no-incest rule. If you intentionally put incest in the game, Patreon considers that a breach of terms and will shut your page down if they find out about it. But if you have a character hooking up with their "landlady" or "roommate", and some mysterious unknown person creates a patch that changes those words to "mom" and "sister", then that's totally not your fault.
(Of course, Patreon also has a no-rape rule and includes things like mind control in their definition of rape, so things are already risky. I don't know if they're more strict about the incest rule or if people just do the incest patch more because it's significantly easier to swap two words out.)
