I concur, though I still don't quite understand the "If we can't  
trip, thus can't roundtrip, thus we shouldn't try to roundtrip"  
argument. Is anyone advocating it that forcefully?

However, I would say that roundtripping is good and valuable and we  
should aim for it as much as is sensible when balanced against other  
considerations.

Even if you never lay eyes on some functional syntax, it is the case  
that the functional syntax/metamodel make a very nice abstract  
interface that is used in the OWL API (for example) and manifests in  
other syntaxes (see the OWLED CNL task force) and user interfaces.

(And, as I've said long ago, I wouldn't mind tightening some of the  
serialization requirements in the RDF/XML (i.e., order of axioms,  
etc.) In fact, I think that's highly desirable.)

Cheers,
Bijan.
