It’s not “of course not.” You said something that is new to me that I’m genuinely curious about. We simply can’t do that here in the States, due to terrain and obstacle clearance, especially out west. Heck, I don’t even know if I could set QFE at, say, Leadville, CO at almost 10,000’ MSL - I don’t think it’s physically possible in most altimeters.
But there are also a lot of traffic considerations, a LOT of airports (many of which do not report an altimeter setting, and VFR traffic doesn’t have to talk to ATC at all, anyway.
So I’m legit marveling at how that works, and it sounds like it comes mostly down to positive ATC control and fairly homogenous airport elevations.
