I don't disagree one bit.  That's why it is important that things use the 
update tool and mark themselves as security updates and whatnot.

It depends on what is broken.  If you don't have the app that is broken, 
you'll get the update.  Only if you have that app that is broken will you see 
the broken deps, and then you can decide whether or not to remove said broken 
app or skip update.

Actually both these could lean in favor of releasing it immediately.  By the 
time the mirrors sync or people do their upgrade the rest of the missing 
packages could have been rebuilt and released.

But all in all I definitely agree this has to be a case by case issue, one 
that is hopefully discussed within releng and the security team.
