Why would you not use this in production?

A global initializer is not a good idea since HttpLog will be undefined in production. Because you're not using this in production, right? :)

If you're running on a PaaS deployment like Heroku, you don't have access to lower level network logging between apps.
So monitoring traffic between apps in a microservices setup is pretty difficult without something like HttpLog.
Heroku only logs out details of inbound requests.

Why would you not use HttpLog in production?
What are the alternatives?
