I suppose the counter-example is synths that include some sort of short sequencer you can use as an LFO, like much of the DSI stuff, the Elektron Octatrack, and the Modal synths.

The number caught my eye because Buchla uses 1.2V/oct
(which happens to work out to 0.1V/semitone instead of the infinitely long 0.0833333333V/semitone).

It's certainly a useful feature. If I see a synth VCF that only has a switch for KBD, I go "Oh!…"
;-)
Slightly better is the OFF/HALF/FULL KBD tracking options, but that's still a shame.
The Pro-One has a knob for KEYBOARD AMOUNT that tracks 1:1 at about "7" on the dial.

Now that we have computer-calibrated control, I like having the option to make the tracking be perfect -or- to dial in a different amount for aesthetics. It bothers me a bit when someone moves the dial on my Pro-One away from the magic "7" because that means I have to re-tune the self-oscillating filter response again. But, hey, that's the joy of a patchless synth...
