Based on the amount of code broken thus far, I tend to agree that P2036R3 
should not be a DR (or perhaps retracted entirely for C++23 until these issues 
are addressed by the paper author). But I agree that we need more information 
on the scope of the breakages, which is why I was sad to see all of this 
reverted without prior discussion.
