Perhaps it's not a good idea (I haven't checked) to change it like that.

But it's fine to change these sorts of test functions even if there's
existing users of it, our test suite isn't a stable API.

Of course one still has to consider outstanding patches, anything in the
list archive we may want to dig up etc., so it's best not to do so
without good reason.

But the "verifying every use" should mostly be just running "make test",
and pushing to the GitHub CI.
