It's difficult to be on all topics. The best way to avoid such miss is to ping when you see no progress. So what's next? They are only inline functions, right? so no ABI breakage. Is it going to require any change on application-side? I guess no. Is it acceptable in 21.11-rc3? maybe too late? Is it acceptable in 22.02?
