With my user hat on, we have done this before -- if inadvertently -- but 
agree it's not recommended nor a habit we should get into.

With RMT hat on,the RMT does have power of forced commit/revert in 
absence of consensus through regular community processes[1]. We did 
explicitly discuss at our meeting today if we were going to make the 
decision right now. We decided that we would come back and set a 
deadline on letting the community processes play out, otherwise we will 
make the decision.

For decision deadline: if there is no community consensus by end of Aug 
28, 2022 AoE, the RMT will make the decision. I know Andrew has been 
prepping for the outcome of a revert -- this should give enough for 
review and merge prior to a Beta 4 release (targeted for Sep 8). If 
there is concern about that, the RMT can move up the decision timeframe.

Taking RMT hat off, if the outcome is "revert", I do want to ensure we 
don't lose momentum on getting this into v16. I know a lot of time and 
effort has gone into this featureset and it seems to be trending in the 
right direction. We have a mixed history on reverts in terms of if/when 
they are committed and I don't want to see that happen to these 
features. I do think this will remain a headline feature even if we 
delay it for v16.

I saw Andrew suggest that the controversial parts of the patchset may be 
severable from some of the new functionality, so I would like to see 
that proposal and if it is enough to overcome concerns.

Thanks,

Jonathan
