Would it be appropriate to link to the Underlying set page here?

Maybe. I haven't done so because the underlying set page describes underlying sets specifically in terms of algebraic structures. I think that a link to that page would therefore just cause confusion.

Yeah, I was wondering about that. Does it make sense to have an "underlying set" page that works for both cases?

Actually, I'm going to ask this in the slack, as others may have opinionsâ€¦
