I measured that my patch (pull request) increases the stack usage of 64 bytes per partial_call() call. I consider that it's accepted for a speedup between 1.12x faster and 1.25x faster.

Attached partial_stack_usage.py requires  testcapi_stack_pointer.patch of issue #28870.

Original:

f(): [1000 calls] 624.0 B per call
f2(): [1000 calls] 624.0 B per call

Patched:

f(): [1000 calls] 688.0 B per call (+64 B)
f2(): [1000 calls] 688.0 B per call (+64 B)
