I thought about that. For a counterproposal, how about we decide that 4.2 (or 4.3, if we're feeling generous) is the last version to support 2.6, and we plan to back this "fix" out when we drop 2.6?

Eh, I think the test has merit. I'd rather just tweak it so it passes and do something more serious in the 4.3 cycle.
