+1 to both of your specific proposals.

More generally, I think it makes good sense to allow dropping support for a platform in the next major Python release after vendor support for the platform stops. Even we say we support something, it will break quickly without buildbot validation.

+1 from me as well. We all only have so much bandwidth and if someone wants extended support there are plenty of contractors who could be hired to extend it.
