> if I use a string interpolation macro (e.g. in an argument to println!, format!, or dbg!) a lot of VS Code tooling that works outside of macros stops working

I imagine this isn't that hard of a problem to solve (though maybe relying on VSCode to handle renames is part of the issue), but low-enough on the annoyance scale that nobody cares enough to implement it. I'm not going to argue there aren't annoyances with macros and that they're harder for tooling to deal with, but I don't think that's a sufficient justification to not have them at all IMO.
