I think you have a point here. Removal of one side of the set of sidebands
turns the FM signal into a sort of AM/SSB signal. During transmission,
FM's robustness to impulse noise will be lost.

This would appear to depend on how sharp the skirt of our hypothetical SSB
(really VSB, now) filter is? I.e., at low carrier deviations there's some
AM and therefore it's not _quite_ as robus, whereas at higher carrier
deviations the filter would be nice and flat and look just like regular FM
in terms of amplitude.

After all... in the presense of some AM on regular double side band FM, most
receivers still perform just fine, don't they?
