Francois,
 
The only advantage would be to tag it explicitly.  Since h323-IDs are not defined in structure, if one really wants to use the MAC address for some concrete reason, we should consider a different alias type.

Of course, there is nothing that prevents you from putting the mac address as a character string in the h323-ID. And it would work with existing versions of H.323 (and other vendors).

I don't see much benefits in adding yet another field.
