That claim is incorrect:

- Some packages have moved files from /(s)bin to /usr/(s)bin. (This
  sometimes requires a compat symlink.)

- More packages have moved files from /lib to /usr/lib. (This often
  doesn't require any extra care.)

Why do you claim that?

Given packages already did such moves in the last years and you claim
this happens in a non-negligible number of cases, could you please
point to some examples where this already happens in practice?
