Because why bother if you're keeping the C? Part of the reason for moving to Go was safety by replacing the C, not just to move away from Python. I'd say the mistake was thinking Python programmers would enjoy moving to Go. I've done it, and it was not enjoyable. I wouldn't mind doing just the tight peformance things in Go instead of C... But using Go for the high-level things that Python is great at, and where the performance is not an issue, is just silly.
