In the same capacitiy, by queueing through the Raid Finder for a Normal Mode raid, you cannot interact in any capacity with those in pre-made groups. There, problem solved. If you don't want to deal with the potential of wiping with randoms, then don't queue for Normals, and continue running them as you are now using your Guild or Pre-made Group Finder.
I honestly don't see how giving options to people is a bad thing. Blizzard didn't nerf Normals in WoD despite people using the pre-made group finder to form PuGs for them, I don't see why that would suddenly change if they allowed people to queue into them.
