Mostly an orthogonal topic, though I do agree that as the JIT matures we
may find we particularly want to move in this direction.  It certainly
makes sense to build in the capability sooner rather than later.

Thinking about ways to negate the other two issues I brought up...
1. Forward-compat; We could produce a smaller distributable package
containing just the script builtin implementations for use on older
versions.  Use some mechanism to mark which versions they're introduced in
and selectively pull them out or something.   Or maybe do that external to
the project (anyone could pull these definitions out and package them for
composer).

2. Bugfixing; I wonder if it makes sense to allow preload files to override
builtin functions.  Then a fix in git could be pulled in before a new
release is ever minted without the need for rebuilds.  Similarly, hooks
could be added to any function to customize them for private installs.
Again, no rebuilds, no special skills required.

Just thinking out loud.
