So, this is an interesting question.  Is Trackback-without-link that 
common a use case?

[In my own personal experience, I don't think I've ever TB'd a site 
without sending a URL (thanks to WordPress doing the right thing), and 
I can't remember ever having received a URL-less TB.  (But my mileage 
varies, apparently.)]

My personal opinion is that "provide a URL if you want to Trackback me" 
is a reasonable limitation to place on the technology in order to curb 
abuse, but if linkless Trackbacks make up more than (say) 25% of all 
valid TBs, I guess it's not so reasonable.
