Of course, if you keep DC away from critical resistors, the shot noise
becomes a tiny signal gain modulation that can hardly ever matter.

It is not quite just a "gain modulation" there is also a phase modulation
component to it. This phase modulation is less than what you would get
from an equivelent amount of signal independant noise.

That surely can't matter until microwave frequencies, and who needs a
ppm-accurate resistance at microwave?
