Functions that are marked for autoloading but haven't yet loaded are
already very lightweight.  That was one reason for using a suite of
files, so the autoload mechanism could take care of ignoring those
that are never needed in a particular session.  Then compdump avoids
the overhead of scanning directories to find those files.

Making it the user's responsibility to explicitly choose what to enable
is exactly what we wanted to *avoid*.  If that's a requirement in order
for the system to be "light enough" then we have failed.

Having a location from which to grab .../share/$ZSH_VERSION/functions/
trees for past zsh releases would be useful, particularly if fixes from
more recent versions were backported when possible.

I would not suggest attempting to create forward-portable versions of
the functions.
