It is not ruling it out. I just wanted to make a point on choosing a
sensible default language. But nothing prevent to have lisp. Just that
if you take the case of Gimp, using Scheme as the default script
language make it even harder to start writing script, while something
like JavaScript or Python [1] are much easier to apprehend if you don't
know them.

The unknown is the biggest fear. A quick poll in the audience showed
that more people new Python or JS than Lisp.

But nothing prevent from having Lisp one the possibilities.
