Well, as you say, those use normally Fedora or Fedora-like distribution.
No need for EPEL to target those.

I'd say those people that only want some new apps and a stable backend
are best served with a local repo for the apps they need in up2date
version or other specific small repos. They can use the Fedora packages
as a base for it; EPEL probably can't serve those people with todays
tools (yum and co), as each and everyone defines stable backend differently.

Those are IMHO round about one of the targets for EPEL -- even if there
is no company behind EPEL, they get stuff missing in RHEL easily with EPEL.

They can use EPEL5 when RHEL6 or RHEL7 are out, as EPEL5 shouldn't move
much anymore and be quite stable.

Hope that clarifies it.
