Marco has a great post outlining why Apple (among others) should require accessibility of an app before releasing it.
The closer to the design end of the development curve that accessibility is included, the better.
Poor or broken accessibility is exactly the sort of problem that Apple’s App Review team should check for: many developers forget to test it, it’s easy for Apple to quickly test when reviewing each app, and it’s easy to fix.
