You’re missing the point. At a Python shop, using Twisted would have been a fine choice. Adding a completely unnecessary Python layer at a PHP shop was not helpful. Yes, there exist people in the world who know Twisted, but they do not tend to work at a place where everything is written in PHP. Adding a centralized choke point and extra network hops to reduce latency was a bad technical strategy, and adding a layer in a language that the existing engineering team didn’t know was also a bad idea.
