The names are all preexisting, so I cannot change them. And the CI infra
does indeed rely on the exact names to choose what to do.

I don't quite know what you mean by counter-intuitive patch structure.
But regarding the duplication for the `group ()` function I agree, it's
a bit unfortunate. My first version did de-duplicate it indeed, but it
resulted in some weirdness in the stubbed case.

I'll revisit this.

True, but I'm simply matching the coding style in this script.

Yeah, as you say, this is another case where I follow precedent. I
honestly don't quite care which way we go in this case.
