I was a bit puzzled not being able to find an OWL 2 specific file/URI
in the OWL 2 related documentation but not any more :)

Thanks for the interesting thread. As an OWL user, my idea was not to
use the owl.owl file as a starting point for new ontology models.
However, I find it useful when it is open on an ontology editor as a
separate "quick look-up kind-of reference card" of the OWL modelling
elements (specially for those less frequently used).
Cheers,
