And if it binds just enough, you might not notice in the sense that the
rotor will still turn, but you'll end up putting
nasty lateral loads on everything simply by virtue of shaft misalignment.

I wonder how much more often you have to swap a rotor in this situation.
Might be kind of a nasty cycle where you don't
even have to tighten a few screws to swap a rotor but you have to swap
rotors more often ;-)
