I don't really consider it a bug; more of the absence of a 
feature.  ;-)  I will consider adding it to 0.7.  (Though it will 
more likely be that I will simply issue a warning if the extra(s) 
aren't specified and the requirements aren't already met; in part it 
depends on whether I refactor to add a more transactional installation system.)

As a way to implement this in the short run, you could place the 
backend scripts in a separate distribution, and list that in the 
extras.  The other distribution could consist of nothing more than 
the list of entry points, and a requirement that points back to the 
original distribution.
