Don't confuse supported with certified.  They are two different terms.
 Red Hat supports many configurations.  Red Hat IHV/ISV partners
certifies a subset of those supported configurations.

I deal with this daily (sometimes hourly) myself.  ;)

I'll point out at least one major oversight in this assumption:  Monitoring
I can also think of about a half-dozen other reasons customers might
tap EPEL here.

Enterprises approve and release community software all-the-time, not
just IHV and ISV software, on their Red Hat systems.  They like EPEL
as it provides many advantages over their own maintaining of upstream
software.

Also remember several enterprises employ maintainers are contributors
to Fedora and EPEL.  Continued interest to contribute to EPEL is very
likely also dependent on working with Red Hat released and supported
releases.

As with Clustering, Directory Services, etc...  Child channels are
additional entitlement offerings from Red Hat that are supported,
certified with IHVs/ISVs in select configurations, etc...

Many "EL Rebuilds" can and have taken the liberty to download the
source, build, repackage and redistribute those additional
entitlements as well.  There's nothing stopping them from continuing
in this role, as Storage now moves from a non-productized software to
one that is an additional Red Hat entitlement.

Maybe I read that incorrectly, but I think that is exactly 180 degrees
from the guidelines.  ;)

This isn't the first time this has happened.  Red Hat has taken a
codebase that it contributes to, even sponsors and/or purchases and
ends up productizing it per customer requirements for support and/or
certification.  It won't be the last either.  It's a delicate balance
that I continually appreciate and thank the EPEL maintainers for.

So the answer shouldn't be to look to the Fedora Project, but to look
to the "EL Rebuild" projects to accommodate this change, like they
currently do for Clustering, Directory Services, etc...  Many claim to
strive for bit-for-bit compatibility with Red Hat product offerings,
so this is their area.

It's still in Fedora.  It can still be in "EL Rebuild" repositories as
well.  Nothing is being taken away from the community.  The guidelines
seem to address this very well.

>From my view, the guidelines were written to avoid this very detail.
Again, it's happened before.  And it will happen again.  They do a
great job of addressing it, to avoid marginalizing Red Hat customers,
at least that has been my experience (first hand, at customer sites
with EPEL deployed).
