I agree with your point and GA pilots need to understand how it looks from the other side.
One of the reasons I stay away from 'big iron' comes from the experience of a radio conversation between me, Socal approach and a United 727 over LA... (something like this, can't remember the exact words, it's a few years ago)
Socal "United XXX you have Arrow traffic opposite direction, 4 miles out of 2700' for 4000'."
United XXX "United looking"
Socal "Arrow XXX you have a 727 opposite direction 4 miles, out of 9000' descending for 6000'"
F3G "Arrow XXX looking"
F3G "Arrow XX visual"
United XXX (sounding slightly concerned) "United still looking"
Socal "United XXX, traffic now at 2 miles"
Socal "Arrow XXX traffic now 2 miles"
United XXX (now sounding worried) "United not visual, still looking"
F3G "Arrow XXX visual"
United XXX (now sounding very worried "United still not in visual contact"
F3G "727 traffic now passing well overhead"
United XXX "Thank the lordy for that, guess you guys can see a 727 against the sky better than we can see a Cherokee down below"
"safe separation" depends on which plane you're sitting in
Felt okay for me, doubt it felt great for the United crew.
However, the old system of the VFR corridor over LAX always seemed to work really well, since traffic types were not mixed and everyone knew where they stood.
