This seems to be a new, popular approach to JS optimalization. For an open-source implementation it's a reasonable approach, but for a proprietary system it usually just delays builds for new architectures.
I think what he is inferring is that it will tend to be delayed on alternate architectures because the company puts manpower on things that will deliver the most bang for the buck(i386, ppc maybe). When it is opensource the people that are affected by the delay have the opportunity to help out.
