Comment 20 for bug 1714244

@Olivier Ah, sorry, thank you for explaining this. This isn't what I want to do, I was just trying to strip back to the basics of what https://www.chromium.org/administrators/linux-quick-start said to do and demonstrate that it wasn't working.

I changed my policy so it says
{
  "RestoreOnStartupURLs": "www.chromium.org"
}

Now when I open chromium, it doesn't go to www.chromium.org. When I go to chrome://policy it reports RestoreOnStartupURLs has value www.chromium.org but says there is an error "Expected list value". I changed it to
{
  "RestoreOnStartupURLs": ["www.chromium.org"]
}
And it works. It is a shame the example code given on https://www.chromium.org/administrators/linux-quick-start doesn't function any more.

What got me to this point was trying to set
{
    "EnableMediaRouter": false
}
to stop chromium from monitoring network ports. Previously I couldn't get chromium to acknowledge a policy is set, but now I see I am able to set policy, but this one is not enforced. Still, I think this is a different problem to this thread. Thanks again!
