I'd say let's just do that once the merge window is done.  A year ago
(in 31abfdda6527) I added a warning for <2.4.x, so raising the minimum
that far would appear to require no thought.  Going up to 3.1 is a step
beyond that, though, not sure if we want to go that far.

Something to ask at the LPC session next week.

Thanks,
