Adding command line switches is not allowed unless there's a good reason for it.

My rationale was to offer non-enterprise users unhappy with default printer
policy a way to address it.
Actually, was it a request to remove this command line switch or to explain it?

I guess the request was to remove the flag unless there's a very good reason to
have it, for a discussion on removing command line switches, cf.:

https://groups.google.com/a/chromium.org/d/topic/chromium-dev/8EjjXUoFqMI/dis...

I believe that allowing users better control is not a good justification for
adding a command line flag.  If a setting is not important enough to make it
into chrome://settings, it shouldn't exist at all.  At least that's my
understanding of Chrome philosophy.

Done.
