Not really. It's a matter that requires some amount of individual
judgement, in some cases. It may require effort, but I think that
that's likely to be worth it.
I won't be the one that quibbles over every little thing.

That's very likely true -- it may be that most individual commands
really wouldn't be any worse off if they just used a standard
alphabetical order. I agree that consistency can be a virtue. But it's
not the highest virtue. There will be a number of important
exceptions, which will have outsized impact. VACUUM, ANALYZE, maybe
CREATE INDEX. So if there is going to be a new standard, there should
also be significant wiggle-room. Kind of like with the guidelines for
rmgr desc authors discussion.
