Describe the enhancement or feature you would like

There is an Other interpreter implementations section in the devguide that lists some alternate implementations like Jython.

But nowadays, Jython is more or less outdated (it still only supports 2.7, and 3.x is still far away). In the JVM world, there is another implementation called GraalPy, which is backed by big company (Oracle) and has Python 3 support, with more active development. Don't be misled by its name, it can be used with the normal JVM.
So I think it's worth mentioning in this section.
