Ok, sure. Why can't we start with something that works with zero styling for one version of one OS on a [fixed resolution] non-touch screen in one language that can't be deeplinked into from other applications for [some people] and figure out if we're even building the right thing before we go "zOMG web-scale" and pretend we're making the next iPhone? I'd also argue that "zero styling" means "standard controls" which often already have good accessibility, and everything (including accessibility?) can be added (re-written in?) after you have a winner.
