There are two reasons I am not in favor of python. First and foremost its packaging sucks.

I have wasted far too much time wrangling pythons packaging systems. Incompatibilities between pip, setuputils, distutils, virtualenv, eggs, C modules, and wheels I have literally given up. I love and use python but I no longer package it and deploy it for others to consume. Try to package a protobuf3/grpc system these days into a .deb, its a nightmare. Even the grpcio devs use docker containers to build packages because python has such a nightmare of a system.

I'll leave the second reason out for the sake of context
