Using delays could ensure that e.g. a sound that is supposed to be at a
particular speaker remains there even for a listener who is closer to the
other speakers which get a delayed signal. But that is not panning, it's
just assigning a sound to a particular speaker direction while using the
others to make it louder, or ensuring that the original (direct, not
amplified) sound determines the apparent direction. Such things are
routinely done in e.g. theatre sound amplification. But you can't create
stable images *in between the speakers* by using delays.
Another thing that can be done while mixing is adding early reflections
(20..80 ms) at a *low* level - this tends to reinforce the effect of the
ampltiude based panning which still determines the apparent direction.

On the contrary, it creates havoc (heavy comb filtering) if the channels
are mixed. Mono compatibility is lost unless you're very careful. It is
possible to create L/R IR pairs that add delays but do not have this
problem, but you don't get those by chance.
A world of exhaustive, reliable metadata would be an utopia.
