GM does not execute early enough to stop content scripts from running,
generally speaking.

You might be be able to do some good, but it depends on both the
content and what you're trying to accomplish.

This is a security risk if there is any opportunity that the file
served remotely will ever be changed.  Don't do it if you don't know
what you're doing and don't understand the risks involved.   A bad GM
script can keylog, give away your first born, and kill cats.  Careful!

Not sure I understand this part.
