See <https://wg21.link/P3475R2>.
Comment 1 Jonathan Wakely 2025-02-28 16:23:45 UTC 
There's a small library part to this (adding [[deprecated]] to the enumerator).
Comment 2 Jason Merrill 2025-03-19 15:36:46 UTC 
I don't think there's anything needed in the compiler, get_memmodel already treats consume as acquire.  I suppose we could remove a few remaining mentions of consume.
