That was the intended behaviour: all PVs specified should be removed.
If any specified are not removed (e.g. due to a conflict with the
-m parameter), then you get the error message:

But the previous behaviour *was* inconsistent - either the command
should have changed nothing and given the error, or it should have
just given a warning level message, not an error.
