Yeah. I think the change is OK from technical POV - it essentially fixes
behavior that is useless/surprising and would just result in raised
eyebrows and bogus bug reports. No problems here.

But the consensus probably was not there when it got pushed ...

Yeah. While I think the objections were wrong, and Alvaro explained that
pretty well in his response, there should have been more time for the
OPs to respond before pushing the change. That's not great.

FWIW, it was mentioned that "your only concurring vote came from someone
with whom you share an employer" which kind suggests opinions/votes from
people working for the same company are somehow less honest/valuable. I
find that annoying and even insulting, because it kinda hints the
company (or companies) are pushing people to respond differently than
they would otherwise. Which I find rather insulting.
