I'd contend that the cert ont _is_ (or at least, could easily be and arguably should be) a low-level ontology: it exists to describe keys and certificates. I don't see a sensible reason why the domain of the things keys and certificates described by it are associated with shouldn't be as broad as possible unless there's a good reason not to  and I'm at this point not entirely understanding what that reason might be.

I don't have a strong feeling on owl:Thing versus rdfs:Resource, except that it's not particularly clear what benefit is derived from restricting it to owl:Thing.

There's a school of thought evident in this thread that one solution is to define another ontology which is identical to the cert ontology except for the domain of the things keys and certificates can be associated with. I don't buy that  it breaks interop. While semweb is, as Kingsley says, "fork friendly", there is still a cost associated with that (and in this case it's divisiveness).
