Not off hand. I know it was suggested in the past tho. ;)

Not a big deal. I sign and push updates almost every day.

So, say RHEL 6.4 comes out. We set our EPEL6 'incompatible upgrade day'
as 2 weeks after that. 

Some people upgrade to 6.4 immediately. Should be ok, as our upgrades
haven't happened yet. 

Some people wait and stay on 6.x. 

2 weeks pass. EPEL incompatible upgrade day arrives, we push updates

People who upgraded to 6.4 already see a bunch of updates that are
incompatible and are annoyed since they already did their point

People on say 6.1 who never applied the point release see a bunch of
updates out of the blue. Perhaps some of these EPEL updates require
newer packages or new packages in 6.4 only, so they just see broken
updates. Granted we have never catered to those folks on old releases

Anyhow, I guess the big problem I see is that some people will upgrade
before our 2 weeks and then have to go through 2 'major' upgrades in a
