So it someone has a problem with a package you backported and reports it in 
bugzilla, you'll answer "not supported" and close the door ? Then we have not 
a single chance to have users accept to use backports rather than ask for a 
rolling release (supposing that we want to stay with stable releases model, 
which hasn't been decided yet).

In my opinion, a backport must be either supported or not exist. Even in 
Mandriva, where everybody keep saying "backports ain't supported", usually 
people try to solve the problems caused by backports.

However, the level of support can be different between backports and updates, 
as I said in my previous message. The differences are yet to define, but here 
are some I see :
- when a critical bug in a backport exists, you can simply update to a newer 
version and see if it's solved
- if the program already is in its the latest version and has an upstream bug, 
you can answer "report the bug upstream" and stop there until upstream solves 
the bug. For packages in release or updates, ideally you have to try to help 
fixing it or work it around because the bug is considered part of the whole
