I've been thinking along similar lines, and there are pros and cons. On the one hand, you get cross-platform portability; once you have an iPhone app written to comply with 3.3.1, there's nothing Apple can do about you porting it elsewhere (or, at least, they haven't tried anything yet). On the other hand, you have to write in a C derivative. It's pretty clear that tools like Unity and Lua have productivity benefits, and you lose these. I think most programmers are complaining more about the loss of freedom and productivity than the loss of cross-platform benefits, which are more of a happy byproduct of working at a higher level of abstraction. So it doesn't really get around 3.3.1 completely.
