Where do you see a conflict?  Those packages are structured to avoid 
conflict with the base platform, but installing into an alternate root 
(/opt/rh/<package collection>) and are normally active only when 
specifically enabled in a login session. That is, they're available when 
wanted but don't affect the system when they aren't.
