yes. and what is the added value of hard-coding arbitrary policies (and
thereby restricting possible use cases) instead of providing a
minimalistic solution (or two, one for semver and one for strings) and
putting a few recipes for common schemes into the documentation?

policy in the classes was always considered a very un-qt thing. the one
counterexample i can come up with is qlibraryinfo, and it is in fact a
constant pita.
