Yes, a mechanical translator was used extensively to create dwt.

Yes.

Calling it a "risk" and "killing" is way, way overstating things.

I don't really see any problem requiring a solution. If you're working on 
optimizations at that level, you ought to be comfortable examining the asm 
output for that and all the other stuff, too. Setting a store on just one aspect 
of switch implementations is a large mistake.
