Honestly I think that kind of explain it the best, generally when it comes to a ship where you really have to find a way to make their relationship work it makes it very engaging to talk about as compared to something that just, kind of slides in and just works. Yeah some people will push the narrative of "only fanon!" but honestly I think finding a "canon" way of making these character work together and have a happy life together is what makes discussing these ships (and subsequently writing for them) so fun.
