Right -- and then Joe and Rasmus had some convincing counter-arguments,
IMO. So, given the outlined Docs patch, I'd like to see what folks can
propose in the form of alternative patches for this topic.

I genuinely don't care. I just want to have something I can follow for the
refactoring of the allocator attributes. :) The trouble I had with Linus's
suggestion is that some attributes don't work[1] at the end for function
definitions, so I'm left unable to follow his recommendations too.
