For example, optimization for bulitin `tp_init` or `tp_new` by FASTCALL was rejected because it's implementation is complex and it's performance gain is not significant enough on macro benchmarks. And I doubt number of 3rd party calls are much more than calling builtin tp_init or tp_new. Of course, current benchmark suite [1] doesn't cover all types of real world Python application. You can create pull request which add benchmark for real world application which depends on massive 3rd party calls.
