15 years is a very long time. For example, bringing Linux 2.2 up to

If this is meant to have any practical effect, I would suggest 10 years
or even 5 years.
True, but VMWare bootstraps off of 2.4.x series kernels and those are
10-12 years old, and the Xenlinux for Xen dom0 patches hang off of old
2.6.18 kernels (circa 2006,) which I suspect are still *incredibly*
prevalent in actual deployments.
I'm not sure what the conclusion is: it's safe to say that there's a lot
of very widely deployed GPL'd software that's 5 or even 10 years
old. I'm not sure a sunset on the copyleft would have any real
(On the other hand, if a sunset provides incentives for third parties to
maintain old software longer than the original maintainer did; it might
discourage slow moving organizations from supporting/contributing to
current development efforts, which wouldn't be ideal. Also unlikely and
