Temperature drift doesn't matter because capacitor aging will have changed
the signal path far more than temperature differences.  Also disagree with
your assertion about repeatability.  Some of my EQs have switched gain but
not much else in the signal path does.  Does it matter that my one or two
octave bandwidth EQ gain is off a little when I can't repeat the gain and
thresholds on the compressors, line amps, or anything else?  Probably not.

People that want recall do their mixing in their DAW these days and use
outboard only for sweetening or during tracking.  But good luck to them in
five years when they can no longer open their DAW files.

I'll stick to my recall sheets and analog gear thank you.

Zero, and I wouldn't buy something that stated such.  The only items I care
for which I care about temp stability are my VCOs and tracking filters.
