I think you're missing here a FQDN not associated with any of these,  
possibly not even existing according to DNS, but within "your" sphere of  
administration - that is, a FQDN which "you" could make exist or associate  
with one of the above, but haven't.

Because I'd still see that preferrable to your case 2, and it's certainly  
a case where whoever decides on the name has control over the uniqueness  
of the name just as for 1.

You currently subsume this under 3, where I don't think it belongs.
