That's not a dependency problem. Nothing breaks. The upgrade works, R 
probably still works, and the docs do suggest running a distro-sync 
after the upgrade if you want to resolve situations like that.

Of course it's not perfect, it's just that I'm not sure anyone's 
suggested an alternative that's *better* yet. The best combination of 
ideas I can see is this:

Use updates/ as a staging area during Branched freezes, and disallow 
pushes if the upgradepath would be violated versus stable and the 
packages currently *pending* for stable.

The thing with that is, I'm not sure it's even viable to write a test 
for that, the 'currently pending' part. Without it, you can't do a 
simultaneous push of an update to stable for all supported releases, 
because the upgradepath is violated for the older releases at the time 
you submit the update. If you want to push the same update to all 
three releases you have to submit it for the newest, wait a day for it 
to go stable, submit it for N-1, wait a day, submit it for N-2, wait a 
day - it's kind of impractical. We struggle enough already with 
getting updates actually shipped (see the updates-testing status mails 
with the list of un-pushed security updates).

(The other thing we could do is have fedup do distro-sync, but we've 
already got a whole bug report arguing about that.)
