This is esentially stating that we cant backport any bigger version to 
mga2 /backports than mga3 will havein /release wich means when we hit 
version freeze for mga3, it also freezes mga2 /backports...

"continue to function properly" vs "don't require that it be tested"

Nothing is "simple" if it's supposed to "continue to function properly"
as it then must be tested.

as the update applet currently works it would show the backport as
an update even if you dont have an earlier backport installed,
defeating the purpose of having separate /updates vs /backports

Tools must work before the backports repo affect them.
