I have no problem at all with the dropping of GPL. Dropping GPL may stop any worries that jQuery at some point in the future will drop MIT in favor of GPL (though they still could do that since MIT is GPL compatible). The license itself is what normalizes the copyrights, so a CLA is just additional bureaucracy. The contributors to jQuery have already all agreed to contribute their code under MIT, so why would they need to do it again?
