That does add a bit of "nicety" to the recovered audio.

do give the AGC loop more gain. Maybe this is what you meant.

Wouldn't that make it an IF GAIN control?

A while back I read a review by the ARRL of a transciver and they
brought up
an interesting point. Modern receivers have enough gain to "hear" the
normal background noise, so beyond that it really does not matter.

In my environment the noise is so high that almost anything can hear it,
my R-5000 often hears S9 level background noise on 40m and nearby SW
bands. (5-10mHz).

The RF gain control can be very handy for reducing noise to the point
where SSB voice comms sound extremely HiFi.

Putting the AGC on slow also helps for a similar reason.
