I have experienced cases, especially in small, tight, ill designed side wall light ports, where at least a 90 degree rotation is a good thing. No electrician would rotate the barrel to flip a gobo, but I can imagine a scenario where a 180 rotation would be desired to KEEP the slot on top. IMHO the 360 thing is just a advertising gimmick and my engineering sense says that once you have made rotation possible, limiting it is more work and tooling than just allowing full rotation.
Don't know about legit theatre on long running shows, but we have had clients in museums and movie theatre lobby displays ask for custom gobos to replace shutters due to drift over time. In these instances the light is usually tight cut on a display, work of art or exhibit area and the light fixture is hung in a very difficult to get-at location.Locking shutters: Never needed it. Just another thing to break. I've never had a shutter move due to heating cooling....
Cooling can be handled by two methods, Air flow (passive or forced) or structure-convection. Structure convection can be very effective if done right. The video clip discusses cool to the touch knobs and controls so, maybe they've got a handle on the cooling issue.
My take on this is they would be convenient, the cool to the touch lauded by the demo may or may not be real, have to see. My take would be to make a Phillips or slot in the top of the thumb screw so it could be hands or tool operated.
As we all know, the reason for the choice in the first place was that LD's and electricians had learned over 3/4 of a century just how big a beam was at a specific distance. The intent was to maintain that relationship. When the S-4 first came out, they didn't want LD's and electricians to avoid them due to unfamiliar beam angles and coverage.
Have to agree here.

This kind of imitation is every where, the cars we drive, the phones we use, the computers we buy.......
