Plus the kernel differences don't seem as huge.
Currently Debian Stable and Ubuntu are using 2.6.18 kernel variations. Redhat EL 5 uses 2.6.18 variation. All of them are released fairly recently.
Old Debian Stable shipped 2.6.8 and Redhat EL 4 used 2.6.9. Those systems are the longest supported distributions out of all mainline Linux versions and now they are basicly obsolete, except as legacy installations. Nobody would want to install either of those systems for new servers or workstations.
Adding new hardware support from backports would be exponentially easier from 2.6.21 to 2.6.18 then trying to go from 2.6.21 to 2.6.8
So in the author's example he was asked about backporting drivers to 2.6.10... probably that means that the device is not even into beta mode yet if they are still working out the details of hardware support. So that is a very odd kernel for anything still in relatively early stages of development.
That kernel is very old now. It will be ancient by the time it reaches market. So it seems very weird that you'd choose that version to work with.
I guess that a good approach would be that generally people will want to keep up with the latest stable releases for as long as they can, and 'freeze' the version as late into the development cycle as comfortably possible.
