We're trying to make them consistent at least in the community space,
without making them needlessly complex or redundant. To your question, I
would posit that in the community space, it doesn't matter. The
container users simply aren't interested in whether they're based on
fedora 21 or fedora 22. The users are after the application, not the OS.
The OS itself is largely invisible in the container ecosystem except as
a host or base container.

In the business case for RH, this could easily be accomplished by
namespacing per release, registry.access.redhat.com:rhel7/foo, with a
link to the rhel/foo-rhel7 if the BU requires it.
