What about USE=python indicating "maintainer's choice" of version? You could then have either python2 or python3 flags for the other one. This sounds a bit more like a policy that should be workable on a longer and more global scale, and similar to what kde and gtk, among others, have done in the past (tho I'm not sure this is exactly right, either, see next). I'd strongly suggest consulting with the kde and gtk projects (others?) and coordinating a global python versioned USE flag policy, as there's definitely some gotchas in doing it wrong, that they've had to live with and ultimately correct as time went on and the preferred version became the new one, with the old one eventually deprecated and ultimately removed from the tree. There's definitely some wisdom of experience there that can save python based packages some pain in the long term (3+ years out, tho it's hard to see a scenario where python2 was actually removed from the tree in anything less than 5, if ever, but never say never). -- Duncan - List replies preferred.
