OpenBSD did this for a while, but they gave up because they weren't doing it 
well enough to recommend it and it did more harm to users to do it badly than 
not at all.

Ideally, you want to get security fixes for all installed applications, but 
nothing else, in this model.  There are two ways of doing this:

- Back-port security fixes to the version shipped with the base system
- Import the security-fixed version into the stable set.

The second option has the problem that you identified: if the new version 
depends on a newer library, then this cascades and you end up needing to import 
a new version of hundreds of ports.  

The first option has a much simpler disadvantage: it requires a huge amount of 
manpower.  Companies like Red Hat can do this because they charge their users a 
lot for this service.  We could probably do this if we had enough users willing 
to pay for the service, or if we restrict it to a set of packages that do their 
own security backports upstream.

The problem with the second option can be alleviated if we make it easier to 
have multiple versions of libraries installed at the same time (this is 
something that the PBI system in PC-BSD does, albeit in an ugly hackish way 
that could be improved significantly with a bit of assistance from rtld).
