Yes, many people want to have free-threading in Python. It might be a good idea to read this thread, and the two PEP 703 discussion threads (first, second), in full (yes, all 370+ messages). Many people have shown why the existing models are not enough, and have presented real-life examples where the GIL was a bottleneck, and sometimes caused a rewrite in another language.
Free-threading might not be easy to implement at first, but it is certainly worth the effort in the long term. If PEP 703 is rejected, I would (in my personal opinion) consider it as an admission that Python is a toy language, requiring “serious” workflows to be implemented in C.
