} That's good, I think that's probably worth doing.

Glad to hear that, however, I have very few clues about zsh wordcode (or
in particular about how to put something into the wordcode back at the
beginning of the command when we reach the separator at the end) so I'm
not likely to be able to change this myself.

There's also workers/42233 and related thread, if we're already going
to be fiddling with wordcode.  (Limitations on the size of a script it
is possible to zcompile.)
