Concurrently supporting 3 releases at the same time is already painful
enough. The ability to drop the oldest release once the next test series
is well underway really helps gather momentum to getting that next
release out the door. Being stuck doing errata for older releases kills
you, especially on larger packages.

We decided long ago that keeping all the releases on the same revision
of the kernel was the only way to stay sane and keep on top of bugs
across three releases. However, this adds an additional burden onto
other developers when upstream breaks compatibility with something
or other, and random bits of userspace need updating.
Stretching out the support for older releases means we have to put
more effort into doing this, or spend more effort backporting
cherry-picked patches (hint: at ~4000 changesets a month upstream, this
isn't going to happen).

The only other two alternatives are dropping support for the oldest
release when the time comes, (ie, what we do now) , or just not doing
updates for anything non-critical. This sounds feasible, but still
gets you into the nightmare of having to cherry-pick and backport
patches, and judging from comments in bugzilla when we've done
similar things in the past, users tend not to like having their
bugs closed with 'not critical, upgrade to the next release'.
