That's maybe a win, but we don't use JQuery that way today. Speculating
about future usability is perilous. We'd need to implement and test, but
see below for some questions to answer first.
If it's important, then people can build such a system using loaders.
But it's at this point completely undemonstrated that exposing JQuery's
few top-level bindings in an imported object beats (for usability,
simplifying old vs. new clients, or any other measure) modifying JQuery
to export those bindings and then importing what the client uses.

Either way, there's a different client code obligation from today's pattern.
It's true you can use today's JQuery as is, but why would you use a new
client API or syntax and require only new browsers or else
trans-compilation? What's the benefit?
