Stuff like motor and switching transients is pretty minor, because most
of that stuff is well below the clamp voltage anyway.

Non power-factor corrected switchmode power supplies propagate nasty
current spikes back into the powerline. This is very easy to see with a
'scope.



Those problems are best solved with just low-pass filtering.

Agreed, and doing so requires a LARGE inductor or transformer.
