The question becomes: how to promote the limited C API? Should it
become the default, rather than an opt-in option?
It would be interesting to find out what is the performance impact of using limited C API, vs normal API, on some popular extensions. This is something that I wish had been included in PEP 384.
It would be great if the limited API could be the default, as it allows building extensions once that work across most python versions.
