Late comment on queer het and related stuff - I always think that it feels very important to apply the insights from marginalised theory/-ists to the mainstream, to stay away from the idea that queers/women/people of colour/etc are so particular they can only explain themselves, unlike the universalist mainstream. But attribution becomes extremely important then (to avoid appropriation), and also I think to acknowledge the power dynamics underpinning the original theory - what happens to them when its applied to the mainstream/oppressors? Sounds like you're doing that in your footnotes though. :)

I sort of feel the same way about queer het - iffy concept, but perhaps useful. There's a collection on AO3 somewhere called "Het, not straight" along those lines. People don't have to be straight and cis to be involved in het relationships, obviously. And fic about queer people are always queer to me. Otherwise feminist or non-normative het might feel more appropriate, maybe?
