This request came in from UserVoice, and I think it might make sense, but I'm also curious if there's a security implication here (i.e. if an admin sets a proxy globally, could a user override it with this parameter?)

Steps to reproduce

Set up a system-wide proxy and run:

Invoke-WebRequest -NoProxy www.github.com

Expected behavior

The request doesn't go through the system-wide proxy.

Actual behavior

The request does go through the system-wide proxy.
