VERY dangerous to go over even 75 mph on, say, the Deegan without these stabilizers/fairings.

Rubbish. Lots of fast, safe bikes have neither. Mine is rev limited to
a top speed of 160 IIRC. You're doing the same thing Wieber does,
taking old limited knowledge and using it to make **** up. I think
Wieber had an old 600cc boxer. Those were something like 45hp. I'm
beginning to wonder if your experience is about the same.
