We've been over this countless times from folks requesting version
numbers. A version number does not tell you what you want to know.
Distros will patch the functionality into whatever version they're
shipping. A 1.1.25 (if it ever happens) will likely have the patch
backported (just applied; no conflict). Querying features has to be
done on a per-feature basis not based on version numbers. See the
proposal on libc-coord.
