Technically, the recoveries we're flashing now aren't replacing the system recovery, they're just put in the system and loaded like any other script. If you try to get to recovery manually with buttons, you hit the default system recovery. If we ever get an unlocked bootloader and an official CWM then we're golden and can overwrite the system recovery. So uninstalling everything else should be a matter of deleting scripts, or just not build them into roms anymore since we won't need to.
It's late, so if I'm talking out my ass I apologize.
I will say, I appreciate all the work and help from everyone here.
