I too have come to that same surmise, Wes, and I hope whoever explains
it [someone always does] does so on the reflector so I can benefit too.
One of my K3's two AGC systems is highly configurable. I finally found
a threshold and fairly flat slope that, for my compromised hearing works
very well. I operate very little SSB, and I notice nothing I'd call
"mush" on CW at narrow DSP bandwidths. If there are multiple signals in
that BW, the strongest one sets the gain, and all the others respond
accordingly.
I normally use AGC-F on CW. Occasionally, with a large difference in
signal strengths, the gain reduction from the code elements of the
stronger signal make copy of the weaker signal at a different pitch
difficult. AGC-S almost always cures that issue.

My reading between the lines suggests that the "mush" proponents think
that after achieving threshold, changing the slope somehow changes the
ratio between signals, i.e. there is less gain for strong signals than
there is for weaker ones.
Frankly, after 60 years of listening to shortwave noise and in my
youth working in a machine shop and hanging around too many alcohol
and nitro burning race cars, my tinnitus practically drives me nuts at
times; I welcome a flat AGC slope.
If I'm all wet with this, I'd like to be enlightened.
