My private opinion, but I think removing GIL is a mistake. Not that many applications will benefit strongly from this, most will suffer a performance penalty. This will take years of attention/effort which could be spent more wisely.
It kind of seems like Python suffers from insecurity / inferiority complex about GIL. I would instead go with the "JavaScript route" of fully embracing the single thread model. Yes, some applications will remain hard / impossible, but I'd argue Python is not a good fit for apps requiring high performance / high scalability anyway. Being somewhat specialized and not supporting every use case isn't necessarily bad.
