Claiming that this is 90% of jQuery is laughable. Removing event delegation, event normalization, support for many selectors in browsers without qSA of course reduces the size, but these features are commonly used and what remains does not, IMHO, make up "90% of the good parts of jQuery".
This is definitely better than Zepto's half-hearted effort, but once he starts adding in the features that people are clamoring for, he'll either have a lot more caveats (like the non-qSA selector caveat), or a bigger size.
The jQuery core/bugs team has been doing a lot of thinking about how to reduce the size of jQuery without severe disruption, and the constraint/cost tradeoffs are actually quite different from this initial jquip effort.
Interesting implementation - they appear to 'pluginize' all of the various components to core. Not sure this is the best approach nor how well it might fair against AMD, but I think as they mention, tests are in order to gauge just how well theirs might work :)
