The reason they don't cross-compile more often is that for the most part cross-compilation sucks - it is impossible to debug through, for one thing.

So, is the issue really the ability to use source debugging? We could still treat Javascript as an Intermediate Language and add a Source Pointer data format that would enable source debuggers in the cross-compiled languages.

In fact, we could build such things into Firefox and Chromium ourselves!

My point exactly. The demand for other languages is clearly not big enough for people to have hacker together an implementation of it on top of what's there today. It can be done, it's just that very few people are busy doing it.
