That was my point.
I was suggesting that it be required that backport requires be 
compatible with newer releases.
In your example, cauldron would probably require the libsomething.so.2, 
so if the backport requires could be adjusted to work with 
libsomething.so.1, we would keep the requires compatible with 
libsomething.so.2.  If that isn't possible, then it wouldn't be accepted.
I'm no expert of course, but it seems to me that it would be generally 
possible as long as there weren't important code changes made to make 
the backport work.
So it would largely be a question of appropriately adjusting the 
specified requires.
