If there's a DR filed with the committee, that gives us something to point our users to as justification. Otherwise, our users will correctly put these bugs at our feet.

If someone could put together a super rough draft of what changes we'd like to see and why, I can definitely work with them to polish it into a final document, get it to the committee, and champion it there. Related question though: what do we do if the committee rejects the DR? I think LLVM and Clang have slightly different pressures here, so we might have different answers.

Thank you! I will prepare an initial draft and share it here.
