This should not be about what you do, or what Andrew does.

This should be a Team decision made to help improve the
quality of the code overall, and that's what I'm proposing.

If it helps people - this is exactly what we do here @ Google.

I know we don't have Google's resources, but we should note
best practices in the area.
