jQuery API for A grade mobile browsers?

jQuery API for A grade mobile browsers?


Rey Bango indicated that a mobile-optimized version of jQuery is "on
the radar" of the development team. I'd be interested in contributing
to efforts in that direction. I've been doing a lot of WebKit-specific
mobile development lately and it seems to me it ought to be possible
to offer a version that works on WebKit, Fennec, and Opera that is
vastly smaller than the full jQuery implementation.
E.g., would it not be possible to eliminate the entire Sizzle engine
(as tight as that code is) by leveraging document.querySelector and
document.querySelectorAll? Another example on a smaller scale is Ajax.
There is no need to branch looking for ActiveX in IE in the browsers
mentioned. FWIW, I'm not as concerned about speed optimizations as I
am about just reducing the size of the codebase. Some of us live in
countries where mobile data is exorbitantly priced! ;-)
Is there an official effort to create such a library? If not, is there
any restriction on someone like me implementing a clone of the jQuery
library focused solely on particular browsers?
