This was true in OWL 1, but will it be in the next version?  We have
tooling examples where the above seems to work (ie, you can still reason
over the instances of, for example, PhysicalQuantitySpace).

This was the point of my previous message: technology moves.  If we gate
the language based on technology, we're in danger of misreading the
future, even assuming we have an accurate grasp of the present. :)

Sure, but that's much more general than your concern above.  I'd
personally like reasoning in general, so much the better if it is in the
ever-expanding DL.
