Exactly! Using of this kind of "delay / Haas based panning" would
improve one big problem on larger setups.
70% of audience on larger setups are out-of-center and 20% percent are
so much out of center that they can't hear audio signal from more
distant speaker
(because of distance and maybe also because of angle).

If this kind of "delay / Haas based panning" would be used there would
be great mono compatibility.
I mean there is still all audio information in both (left and right)
PA speakers.
So very out-of-center listener still getting all audio information...
even mono ;)
