Ugh, here we go again, ok, so those that say that they can add it through a patch, that's false, Patreon doesn't allow people to circumvent their rules, their rules apply to any place the devs put something Patreon related, their discord and their own page have to follow Patreon's rules.
The whole idea of "But other devs do it" doesn't matter, they don't received a report of said content, that's all, the moment a user reports a dev of having a patch to add something against their rules their page will be put on review, or if the thing they add is something serious they can ban the game entirely or even worse the dev, everything is up to who they go against, there are open minded "mods" on Patreon and they won't follow a report and just ignore it, others will try to crush the game at any opportunity they have because they are prudes.
Patreon makes their ToS ambiguous for that reason, so they can change every statement to their advantage. Even worse there has been reports of some devs that got their page taken down because Patreon representatives saw patches in this page (F95).
I'm not trying to argue here I'm just giving you what has been happened with some of my dev friends in the past, and why Jikei and Phreeoni (Nocht) have decided to not do a patch. It isn't worth the risk for them, not that it wasn't worth the hasle, they wanted to do it too, but as it was minimal content they decided to not develop it further.
