> Until recently(?) the primary JIT back-end for PyPy was, in fact, still the JVM.

This sounds false. The PyPy Features page does mention that PyPy will run on the JVM, but that it is incomplete there, and in particular they don't have their JIT ported to it yet. Do you have any source on that?

PyPy has had experimental backends for JVM, CLI and LLVM, but AFAIK, none of them have ever been the primary backend.

It also had a JavaScript target in the beginning. Pretty cool. But I understand why they had to drop those to concentrate on their primary RPython backend. Since building a fast, self-hosting compiler was one of the main goals of the project (another major goal being to create a JIT compiler framework for any language to adopt, which PyPy is great at but no one knows it).
