It's reasonable to support one great programming language along with Java, which is kind of a market standard.

I didn’t say it wasn’t reasonable, but it is a downside for those wanting to do something different.

I’d prefer they tested emitted code, that way you can use anything you want.

They'd need to maintain trusted sandboxed environments for every supported compiler/interpreter. That's a lot of work.
