Not sure this is worth it. A mail on mojo-dev should be enough

On the other end, did you check that we didn't have documentation that
references this?

I intended to set the mapping, send the email, and remove the mapping a week
later. Might save some people some time. I'm happy to skip the mapping part of
you or James feel strongly that it's not needed.

As for the documentation, I update the READMEs in this CL. Drive search for
"sample_app" didn't give me any hits.
