In my opinion it would have introduced even more fetishes and taken them further
I disagree here, "More" would certainly always be an option but with the goal of having three weeks of game time probably wouldn't have been feasible to cram in.
But "further" I am happy that it's not. Not because - depending on the fetish - I wouldn't like it in general but because I think that this game serves a useful purpose in showing many kinks which more vanilla players may not know that much of without going to the extremes. That is too rare already in my opinion, and here we're even running a small gamut of kinks in this way.
If I am not really accustomed to, say, the SM part of BDSM, getting a glimpse at what direction it takes and then feeling "kinda like that, maybe there is more somewhere out there" could be nice as an introduction. If you introduce this by taking every girl into a dungeon and whipping them until they are bleeding and pass out unconsciously might turn you away without really knowing that it doesn't have to go that far.
Again, I like some more stuff in games as well, but a game that introduces the concepts of a few different kinks without immediately overburdening has its value. Some - like me - get into Whisky with a complex Islay single malt, but others prefer to start smoother and then try out a bit more peat. And not everybody gets into Jazz with the most complex free jazz improv but maybe better starts with some jazzy-ish lounge music.
And also in general, not everybody who likes a certain kink needs it to go as far as it gets. So despite liking DS many games may go too far and having one with a bit less can be a nice change.
