I don't see how this is in any way unique to GAE. Sure, GAE requires some specific optimizations to get the most out of it, but so does everything else. Someone with a lot of GAE experience and close to zero classic LAMP experience could similary complain about how time consuming it is to learn all the optimization tricks of that stack, compared to how easily everything just works with GAE.
