For some projects, sadly yes there is. Fedora's not approved or come up
with any policy around software collections yet. For some projects that
rely heavily on software collections, this is problematic. In other
cases, the code may already be in fedora but simply needs to be 'brought
back' into the EL ecosystem. Further, things like the Xen4CentOS project
may need an updated or patched libvirt, where there may not be any
interest upstream because Xen isn't supported there.

Docker is also example of needing something newer. We're working to try
to keep an updated 'upstream' docker instance available for users who
want it. Right now in -Extras we have 0.11 (soon to be 1.1.2) in keeping
with RH, however on the community side there's a tremendous push for a
newer docker. Lokesh (the fedora dev responsible for docker) has been
working with us to ensure that we have a current build as well. In this
case the code lands upstream in fedora first, and is then built for
CentOS as appropriate.

Fedora should absolutely stay the upstream, but it doesn't always make
sense in every single case.

It does indeed. This circles back to a discussion several months ago on
this list about tiered repositories, best practices, etc. We've known
for a while that this would come up, but before it was mostly just
discussion and theory. Now we're looking at putting it into practice
with deliverable content.
