You are the only person with the view that capacitor load testing 
of amplifiers is a useful tool to make amplifiers as stable as we may
want them.

Unconditional stability is found in very many tube and SS amplifiers.

We don't listen to square waves but we use them to test amplifiers.
And we use C loads to TEST them, and adjust them for
minimum square wave overshoot and minimum unpeaked sine wave response.

See my other recent post.

There ARE situations where complete stability with NFB isn't 
necessary, for example in a radio AF amp where 
the speaker used will always be the only speaker connected
and located within the chassis cabinet.
