Also, on a pragmatic level... I think an ecology built around scripting in multiple languages (because you have to support emacs lisp -- that's what things are written in now) will actually make it more confusing to do future development, and now debugging/extending other people's packages requires competence with both languages -- potentially, anyhow. You end up fracturing the community.

Something as simple as getting advice for solving a problem on web forums would also be affected by the dichotomy. I think that might be worse for newbies.

Still, I think it's fine to run the experiment, and see if that is what people want.
