Sorry, but that is not what I meant.

I think we do want the endgame to be that .clang-format defines how
the code should look like.  It's that we are not there yet, and I
think that is what we should say in this comment.

	Note that this style definition does not yet quite reflect
	how we want our code to look like, and adjusting the rules
	to match our style is still work in progress.  Do not
	blindly adjust the style of _existing_ code, without
	checking if the code is styled incorrectly, or the style
	definition in this file is still wrong.

is what I should have suggested when writing my response.
