Um, isn't the point of Zepto a modular jQuery that may not support 100% of what jQuery does but it tries to at about the same speed (or better)?

I think modern jQuery is already modular (or semi-modular) and you can download a build of it that contains the features you want.

But honestly, if you load jQuery from a big-time CDN, chances are your users already have it cached and don't need to load anything.
