It is also easier for Python devs to pick up Go and become productive than with C. I suspect SF had more people that could move quickly from Python to Go than those who could add features to the C lib. This is from personal experience where Go is used when performance is needed, and the end result is a single program, vs a C lib and a Python wrapper, gaining some level of simplicity along with the needed performance. We don't get quite the performance of C, but we also don't need to include memory management. Sort of a happy medium between Python and C.
