If we are adding a doc about best-practice for maintainers, I think we
should be encouraging people to test regularly.

I think our testing story is too shaky to make that a requirement.
Differently put - I was never able to get good upstream testing running
when I worked for a vendor myself so I wouldn't know how to draw 
the lines.
