I don't think the argument applies to 2.7 as much as it applied to
earlier releases: 2.7 will have a life time of 18 months perhaps (I
think we still need to decide formally against 2.8, and also decide
when to make the last 2.7 bug fix release). There is some likelihood
that by the time people can agree to drop 2.6 support, 2.7 will be
out of bug fix maintenance already (*). I'm fairly skeptical that people
will be interested in adding new code to specifically clean up their
(*) just as it happened with any other release: people are now dropping
support for 2.3, when this got out of security fixes a year ago. By that
measure, people will drop 2.6 support in 2015. I think there are
*really* good chances that many packages will drop 2.6 support along
with dropping 2.x altogether.
