I sort of do that - I have a custom local repo and when something in an 
update causes breakage (can't remember the last time) I google for the 
problem online and find a fix and rebuild the src.rpm appending a .1 to 
the end of release so it looks newer.

So I don't exclude things from CentOS or EPEL, I just add things to 
it... right now all my custome repo really has in it is solitaire and a 
texlive fake package that fakes out packages with require texlive (I run 
vanilla texlive managed by their utility, I don't like texlive as a 
zillion different RPMs)

Honestly though I haven't personally experienced a breakage as a result 
of a package update in years, and when it happens it almost always is 
EPEL where the maintainer did a major version bump.
