I noticed that the four lenses I most recently purchased all focus perfectly with no micro-adjustment. Well, ok, one is the 24 TS-E , and manual focus using LV doesn't count, but the 300/2.8 IS II, 70-200/4 IS, and 70-200/2.8 IS II all nail AF right out of the box. I tested carefully using the "moire target" method, and could not improve on the results. In contrast, the majority of my older L primes and zooms benefit from a few points of MA, and the 135 L (my oldest L) gets +14 to become a super sharp lens.
I mention all this because we used to hear complaints that Canon introduced AF MA to save themselves service requests and allow lax quality control standards. It could easily be a matter of luck for me with these recent buys, but I think there's a chance that AF function is becoming more uniform, and certainly little to suggest that it is less well calibrated than in the past.
