If we want to make use of GIO, we would need  2.28 at a bare minimum.
This is present in RHEL-6 vintage onwards.

Unfortunately, if we want to make use of GIO with TLS, then we would
realistically need to have 2.38, since the changelog shows there are
some pretty major bugs in the TLS impl in earlier versions. eg you
could not read and write to a TLS socket at the same time prior
to 2.38 [1] :-( So that version of GIO, with the glib-networking addon
to provide TLS, would mean only running on RHEL-7, which feels like it
is so new it would likely be a showstopper.
