Right.  So I am asking: if a 3.x user volunteers a 3.x patch and a 3.x 
core developer reviews and edits the patch until it is ready to commit, 
why should either of them volunteer to do a 2.7 backport that they will 
not use?

I am suggesting that if there are 10x as many 2.7only programmers as 
3.xonly programmers, and none of the 2.7 programmers is willing to do 
the backport *of an already accepted patch*, then maybe it should not be 
done at all.

I am discussing the situation where there *is* a near guarantee (if the 
backport works and does not break anything and has not been so heavily 
revised as to require a separate review).
