I am almost certain that if Satoshi had originally coded a block limit doubling every 2 years along with block reward halving every 4 years then this would never have been discussed or even pondered in so much questionable detail. People would be like, "Oh yeah, that's the way it works, let's just deal with now".

gmaxwell: thanks for your timely input on the necessary decentralisation quantification.

Do not forget that the hard-coded fees constants fix should be addressed simultaneously with this issue since they are inter-linked .... or we'll be back arguing about that eventually also.
