That would IMO go in the commit message, as it's meta information
quite relevant for git history, but rather noise for the current
code.

It would not break existing setups, so it rather would be for adding
a new realm, or updating that part of an existing one only though?

That I'd see OK to go for the `"break" it, release it and see if some
one complains things` route.
E specially as it's not really a strict regex, any complaint would
mean that the PBS one needs to be further relaxed too.
