Yes, you turn it off.  Once the change to enforce this rule is merged
into hacking, other projects can start refresh their hacking
dependency (e.g. upgrading to latest version).  The patch to update
the dependency has to turn the newly added check off and then
consecutive patches can fix all violations in that project and then
turn the rule back on.

I know there are at least 30 other violations of this rule just within trove, and I imagine larger projects probably have more.  I'd hate to be the target of all the ire that sudden rejections of every commit would cause.  Do we have a way to make it off by default for some period to let the projects all clean themselves up then turn it on by default after that?
