For this idea to be taken seriously, I think you would need to create
such a version and benchmark it VS the all-in-one jQuery.js. IF you
can show significantl performance differences, then perpahs your idea
could gain some traction (though I'm not in favor of it). But if we
are only talking about *a few milliseconds* difference in normal use,
then this would not justify the increased maintenance and code
required at every level - development, testing, documentation, library
linking, etc. IMO, the performance improvemetns would need to be
significant and *noticeable* to justify all this extra work and
complication. Making users add branching logic to every page is not a
small matter.
My 2-cents.
