That'd be back-porting, not forward-porting.

Anyway, in Debian we use a bit different approach usually.  Namely,
instead of backporting lots of stuff resulting in a BigMess(tm),
we provide more recent upstream versions of the software but
compiled for previous (stable) debian release.  This mechanism
is named "debian backports".

The stable release itself does not receive any large feature
updates.  It receives bugfixes, but only important ones.

Besides, this scsi stuff doesn't really matter much -- it
helps in some very rare situations (for example, sometimes
this way it's easier to migrate from vmware to qemu), but
that's about it.  So I don't consider doing backports
especially for scsi.  If the new version backported to
debian _also_ fixes scsi issues, that's just a side-effect.

Thanks,
