Actually, it's the solvent / thinner that's mixed in with the propellant
and primer. With sufficient solvent, it would be trivial to could get
the same kind of pitting with an airbrush that uses Nitrogen or inert
gas for the propellant.

Oh, believe me, I shake and swirl the can for several minutes before
spraying, then clear the can. I even keep hot water ready between sets,
to counteract the cooling caused by spraying. And I sorely doubt that
Myr and the other painters are ignorant of how to properly use spray
primer.
That doesn't change the fact that automotive primers are "hotter" than
hobby primers. Nor does it change the fact that GW plastic is
relatively more sensitive to the amount of solvent in the primer.
Now, perhaps you've found some other techniques that are suitable for
using hot primer on sensitive plastic, and simply aren't aware of what
you've been doing to get it right.
But I can tell you for certain that if one is primarily experienced with
using hobby primer, automotive primer does require different spraying
techniques to avoid pitting of GW plastic above and beyond merely
shaking and clearing the spray can.
