Seems the obvious response for those who are disappointed they can't migrate their league's history is just to not purchase.

The only real leverage anyone has is their wallet. If everyone buys the game, what incentive is there to make the history engine backward compatible?

There's always a list of possible features, Markus is picking the ones that people want and will pay for. Make importing history move to the top of that list, if it really is important (which I think it is, and I have not yet purchased, and this is one reason I'll hold off longer).
