You reach out to the distribution maintainers to get help testing:

https://sourceware.org/glibc/wiki/MAINTAINERS#Distribution_Maintainers

We do this semi-regularly in Fedora Rawhide (which tracks glibc master)
in order to test new condition variable implementations, the new Unicode 8
support etc.

We could carry such a patch for a cycle in Rawhide and see what happens.
We are still building bootstrap infrastructure [1] which would be faster
to give you an answer. In Rawhide it will take months to churn through
the repo and developers might patch around it (even if I post about it
to Fedora Devel).

At present I have no opinion on what we should be doing here.

If you can make a conformance violation out of the present situation then
I'm happy to see a fix go in, *but* we better have a documented answer
in our release notes for users that need to fix packages, like we did
when we moved to _DEFAULT_SOURCE [2].

Cheers,
Carlos.
