The fact that ‘any’ is not about which versions are supported, but about the
fact that the resulting archive is identical for all supported versions was
confusing me when reading that syntax, but I got it now. I also didn’t get from
the documentation yet that '{darwin any}' and a version range check like
'{darwin >= 16}' could be combined like that, but that’s good to know.
