I remember that too - and was SO excited - because taking ai files (such as a fake UI layout) with thin 1px to 4px horizontal lines and slightly tilting them in 3d space is a huge aliased mess in AE. It's something we did a lot of on 'Ender's Game' - and it drove us crazy.
Unfortunately, the 'more accurate' switch didn't do anything to make the situation better in that case. Neither does the new CC antialiasing control. :-(
But an improvement in that area would be hugely welcomed!! I'll file an FR.
