There is actually a formal LLVM decision making process:
It has only been used a few times before, but may be worth using here.

I think this is pretty key, especially with infrastructure work.
Infrastructure tends to be neglected because it's rarely the core of the
project. And since it affects developer workflows, it tends to be
contentious. It is very easy for people to come up with objections or muddy
things enough that no progress is made at all.

I would push back pretty strongly against this. Obviously the entire
community should be able to voice its opinions, but at some point some
people are the ones who are actually implementing things. It doesn't matter
if the community comes to some consensus if no one is actually willing to
build that thing. Again, and especially with infrastructure, it is very
easy for people to complain about any solution, but much more effort to
actually contribute to the one they prefer.
