Makes sense to me as well, especially since I don't see any drawbacks for non-accelerated scripts. I also think some of those applications that didn't show any gains could be trivially modified to make use of it. Moving from conditionally loaded stuff to lazy-loaded is likely to speed things up. Depending of course on how granular the conditional loading is. -Rasmus
