mcrews, you say 3x the light is too much? Not so.
I can legally buy and use +50% H7 bulbs, +80% bulbs, +90% bulbs and +120% halogen bulbs. +120% is 2.2x brighter.
How long before we see a +200% halogen bulb (= 3x brighter)?
We don't need to wait for that 3x brighter bulb because it already exists as a HID.
So suddenly at 3x brighter you want to decree it is suddenly illegal? Where are you going to draw the line?

There is such a lot of fuss being made here. There is no fundamental reason why an equivalent sized arc can't safely replace a filament in a halogen projector lamp which HAS a cutoff shield.

I agree, a lot of people do it badly. And it probably shouldn't be tried as a retrofit to a reflector style lamp with no shield.
