Hi Chris,
I don't have pain nor is anyone suffering. While I'm sure my sponsor is not pleased to have to expend extra effort to achieve their goal, I would not go so far as to use the term pain. New major features are rarely perfect in the 1st round. Please recall that it took quite a bit of effort for 32 bit machine code to be perfected. Many still shy away from it - "just cause" it got a bad reputation in the beginning.
