This has been done! Many times, most recently with Mojo. It sounds like you're the target user but don't use them, so if you're interested you could help them out by telling them specifically how they don't meet your needs
Nah I’ve given up on Python wholesale these days, and don’t operate in AI stuff anymore either, so not a lot of need for any of the current Python specific libs. Basically everything I write for work or hobby is all Rust now , but I’ve written more than enough Python that I’m still interested enough to follow the developments from a distance. :)
