Well they had them on GP two strokes so the answer is out there. IIRC it was something nearly as sophisticated as a sidestand switch which turned off the ignition for a while.....

Pricey though. Other options out there, even people making their own.

Part of the reason that the HM unit is quite pricey is that it is triggered using a inline sensor on the shift rod. The cheap (but functional) way to do it is to trigger off something like a rear brake switch that is attached to the shift lever, so once the lever moves very slightly it is triggered.

Then you need the electronics for it which you can make yourself if you're keen on it. Essentially a 555 timer or similar provides a momentary pulse which can be used to switch a relay that cuts power or signal to the coil/s.

There used to be a piece of equipment called the Battle Shifter that worked on the early 1990's RS125's.

Way earlier than that, it was just a piece of hacksaw blade you pressed with your thumb to earth out the ignition while you changed...In the 70's you could buy a pressure switch which took the place of the shift drum detent spring assembly. As soon as the drum moved and pushed on the detent, it cut the ignition.
I still think that's probably the neatest.
