Of course - this being Open Source and we being volunteers, we work on what we want to work on :-). I generally see that doesn't happen much for projects operating this way, though. My perception is that typically once 2.7.0 is released, work dies off quickly for 2.6.x. As mentioned elsethread, what the distros are signing up for (right or wrong) is to put a stake in the ground on a certain version and to select specific patches for fixes alone. If we were to do the same, it may be a duplication of effort.

Now... That doesn't preclude us from operating like Ubuntu does, for example, with their LTS style releases where we do "2.6.x will get fixes only for X years, but 2.7+ will get features until the next LTS cut". I think that idea may be what you have in mind. So, in that world we have three long lived branches: trunk, release and LTS. I can see us operating in that way... and to make backports less cumbersome, we could further declare that a fix accepted in STATUS for the LTS branch is accepted also into the release branch.

One more thing to point out that I didn't explicitly say in the previous message is that this suggestion implies the release branch regularly gets cut from trunk (rather than growing and diverging on its own). This helps avoid "locking" features in trunk indefinitely because of the time between Maj.Min bumps.
