A couple more comments:

1. I'm very happy for Zile to be used as an experimental platform.
It's increasingly obsolete as an actual editor (Emacs starts up fast
and runs on most things), but I still maintain it and it has a test
suite. Hence, it's good for making experiments that change the
implementation but keep exactly the same behaviour.

2. The Lua version will shortly become the primary one. In a way this
makes it easier to experiment on the C base, because the C will change
increasingly slowly, but also do not neglect the possibilities of
experimenting with the Lua version. It's much more convenient to
change; Lua is happy to talk to C, so it's transitively happy to talk
to other languages that talk to C; and finally, with respect to Guile
in particular, don't forget that Guile has experimental Lua support,
so there's an obvious way to short-circuit C.

Anything I can do to assist experiments, and ESPECIALLY experiments
aimed at improving GNU, please don't hesitate to write to help-zile or
