Are these any useful without gil-refs?

I don't think so, in general I think it's helpful to not have the structure of the type objects be constrained by AsRef / Deref.

Oh I see what you mean, I've duplicated too much here. Will fix later!

Actually we still have AsRef / Deref here in this macro on main, maybe we could remove later (i.e. in 0.23 or later) but I think we have to leave these here in this PR for the patch fix. AsPyPointer (just below) should be removed though, I pushed that.

Sure, removing them from main makes sense. I don't think these can ever be used now, because there is no way to construct a literal PyAny (or similar)
