I guess this is the point I was thinking of as well. as a former MX racer, I had little experience of a roadbike. same applies to cars, my escort was gutless, but at the same time kept me out of trouble.
no new rider or driver can competently deal with the power in a litre + bike or something like a GTR. Yes, we have all had the confidence that we are better than schumacher or gardner, but at the end of the day car and bike craft take time.
if it reduces the likelyhood of someone getting into trouble with a big hit of power, then what is wrong with that? the other thing about roads, is that there is more than just one car or bike to contend with.
