This PEP makes me realy exited and I would love to see pyodides ffi beeing integrated in cpython.I maintain a similar ffi which is loosely based on pyodides API and I would love to stop maintaining it and just switch to the ffi discussed in this PEP.
This would defragment the python-wasm ecosystem a lot, because atm there is the pyodiode and emscripten-forge world, and they both use some ffi which is already somewhat similar but not 100% the same.
