There has been funding in recent years to fix the quirks and improve performance. The Faster CPython project has had good outcomes towards achieving these goals.

Python 3.13 will have a JIT, and true threads. It'll likely take a couple more releases for these features to be stable and utilized throughout the stdlib and the wider ecosystem. In a few years, performance and quirks will likely not be an issue.

Threads that slow down single thread performance by 50-100%. The "faster CPython" figures are just marketing as well.

Whenever I run some benchmark myself, I do not see any improvements over Python 3.7 and the horrible numbers for the threaded build.
