No comment? :(
It has been stated that there will be a new girl moving into the vacant room, but no further details have yet been given as of yet.
Also, I believe Android has a footjob repeatable scene as well, but I could be wrong since I haven't been able to play since V. 0.15, and can't remember all of the repeatable scenes atm. As far as the other kinks go, they are indeed more unusual kinks, and a major turn off for quite a few people, myself included. I personally believe that more niche kinks like that aren't the best idea, as some people that dislike them may start raging here in the comments, like NTR haters when a game decides to include that particular kink.
Well it wouldnt be that hard to just not play the parts youre not into. Add a pee warning or foot warning, with a skip to the end of the scene, and voila. I mean Im not into femdom at all and its quite a turn off for me, yet that doesnt mean I mind if we get more, because I can always just rush through the scene if I dont like it.
More options and kinks will never be bad, so I stick by my request for more pee and feet, with the option/warning to skip for those not into it.
The foot fetish I don't see as a problem, its the watersports that can be a divisive kink. I'm sure you've seen all the heated debates about NTR in games, and people raging and saying it's the worst thing in the world. Heated debates like that can potentially drive away people who may have otherwise been interested in a game, simply because they don't want to be part of a community like that. Also, I'm sure that you have looked at the tags on other games, and seeing a kink in the tags that you don't like, have looked past it for something else to play instead. It's the same effect, drives away potential players due to them not knowing that it's easily skippable because they didn't check.
The inclusion of such a niche kink can be detrimental to a game's development, and if the dev themselves isn't into that particular kink, there is a good chance that the implementation will be extremely poor quality. In the end, it all comes down to the dev themselves, as they usually (but not always) make the game that they want to play, including things that they enjoy whether other people also enjoy it or not.
