Every single project which has tried to drop the GIL has failed in some way. It's not some "esoteric features", it's fundamentally a hard problem that implicates the entirety of the python object model, python C api, scoping, imports, and GC. I think multi-interpreting is the way to go, but that still would require a framework for ensuring safe memory access. Speaking of Go, I always thought it would be neat to write a python implementation in Go, but leverage Go's GC, and implement the 'go' keyword/function for easy parallelism. But you still have the problem of scoping and memory safety. Or similar idea but with Rust. Something tells me that isn't a trivial undertaking, especially if you want all the libraries, which is 75% the point of python.
