I have asked about using RPython as a generic standalone language before. I think the official statement is that is was never intended to become one, and it's really a very minimal subset of Python (so basically no existing Python code will run, it would require heavy refactoring or complete rewrite), and it's only specifically those features that they currently need, and it might also be a moving target, and they don't want to give certain guarantees on stability of the language etc.

Once you consider that you anyway need to write very different kind of code for RPython, then maybe just using Nim or some other language is a better idea?
