Subject Re: [DISCUSS] Blocking merge button in PR
Date Mon, 21 Oct 2019 17:45:28 GMT
All committers have to right to commit and all committers have the right 
to revert.

It is ALL for the good of the project. Now, of course, I imagine we 
won't apply scorched earth policies, but every committers should feel 
empowered to be able to revert a bad merge, if it hindering the progress 
and health of the project.

Of course, contacting the original committer to revert the merge, is 
preferable, but sometimes things take too long and a kindly worded email 
to the committer, letting them know the merge was reverted and for what 
reason is all that is really required in the end.

the original committer?  If we feel individual ownership of commits, we might hesitate to
revert someone else’s commit, even if it broke the build.  However if we feel a strong sense
of community, we might be ok with an anyone-can-revert policy.  A revert does not have to
imply shaming...
