If IBM can make this happen for their OS, and Red Hat certainly supports such a process in the Fedora line of releases (including the ability to list additional repositories for remote installation as part of the process), they could certainly make it a supportable option for the RHEL line.
The upstream supports nothing as to Fedora, and indeed, members of that project regularly (and seem to gleefully) break forward compatability
But you are missing the point -- WHY spend the engineering effort on trying to support such Major 'upgradeany's? A new deployment takes mere minutes for a commercial shop, and by NOT supporting such explicitly, the upstream avoids much support and engineering load.
[I say this having done an 'upgradeany' and run into a later 'nss' in C5 than the C6 initial media provides, that required some head scratching, and a nasty workaround, to solve over the weekend]
