What about renaming the files to *.jsx?

What about renaming the files to *.jsx?

The issue is not that particularly. It's that JSX is rather oriented towards user-readability which is fairly very low on the things we care about on computer generated code.

The strong reason for moving away from JSX is that it breaks JS into two lands, JSX and JS, and we have to have interactions between the two very carefully. If there's no division between the two then code gets a bit easier to maintain.
