For me: I still don't know how to integrate clang-tidy into my development
workflow. I'm open to pointers to documentation/etc.
Because the tool would need to apply judgement to when this makes sense.

Yeah, I don't think we can automate it entirely, but at least it might
lower the writing cost to make it easier for folks favoring auto for
writability where community standards would prefer the named type. Nice
thing about clang-tidy etc is if integrated well, it should only flag on
code in the current diff, and only as a suppressible suggestion not a hard
I think if folks want to work on that, it'd be appreciated, but I don't
think it changes the discussion around what style we want.
