We do provide a number of years of overlap- 5 years in fact. I believe
that's an entirely good thing and gives our users a chance to manage
their upgrade paths from one major release to the next.

Increasing that overlap to 10 or 15 years, however, doesn't make a
hill-of-beans worth of difference, in my opinion. Either they're
tracking the releases that we're doing and making changes and adapting
as we change things, or they aren't and won't ever unless they're forced
to, instead preferring to make us carry the burden of maintenance on the
backwards-compat pieces.

Thanks!
