Proper poly pairings would go a long way, as well, as so often it's just an open relationship/people not minding, which isn't quite the same thing.
I have a feeling we'll be getting the latter, simply because, again, it's so much easier than anything else - so easy that modders have been implementing such things in other games for years. But it's interesting that a few games outside the indy sphere are starting to at least attempt it.
Stop dashing my hopes! *laughs* But no, I do understand the issues with it. It's a little tragic, truthfully, but there's only so much dev time and the more niche an option the fewer people are liable to see it, arguably creating some sort of worth based around things that are a more common denominator. We have been seeing a few games here and there add them in, though, both in actual pairings and background. I Was A Teenage Exocolonist was really inclusive and well designed that way, for all that it is (mostly) a VN so is perhaps arguable if it deserves placed in a similar level of consideration.
