Is there a way to monitor any network calls made by plugins?

Given that there is already the network tab and external tools to view network traffic, writing a plugin would be a unecesary.

There have been discussions about this in the past:

TLDR: Checking the security of plugins with another plugin is either a really bad idea, or straight up not possible.
