Yes, it was very interesting to me that a term I had quietly thought was commonly understood to be what I meant by it had different shades of meaning for other people.

I'm torn on the concept of "darkship" being widespread, to be honest! It might be a helpful way to signal that you didn't think it was a great and emulatable realationship dynamic for real life, but I also feel like it might have the effect of like... implying that shipping something that way was fundamentally different to the standard way that something Should be shipped. Like (and this is maybe a flippant comparison to make, but also I am trans, so I think I'm allowed) I really didn't like when trans* was being used as an "inclusive" term, because I felt like I, as a non-binary person, was being pushed into the asterisk and implied to be a new and fundamentally different thing to people who were simply "trans" if that makes sense.
