Right, so I believe the rationales for the differences are:
  - interfaces have the "able to be a C/C++/Java/Python identifier" rules
  - bus names can have hyphen for dcop compatibility iirc but were
    originally the same rules as interfaces - maybe we should say
    hyphen is discouraged ? (do I remember this right?)
  - object paths don't allow hyphen just to ensure a consistent
    convention, but there's no expectation they'd be used
    as an identifier so they can start with digits
