Genuinely curious, I don't know much about java. But if the JVM is good enough to implement full way-more-performant-than-python languages like scala/kotlin, shouldn't it technically be possible to progress the language without mucking with the JVM internals at all?

It’s been tried but dynamic languages are not very well suited to the JVM, but progress has been achieved with things like ‘invokedynamic’. The finer issues have to do with things like numeric representations, C bindings, class loading etc. still there are implementations of Python and Ruby on the JVM but they’re not especiallY popular as you can’t run the big libraries.
