Sorry, I realized after sending that it may have been unclear.  Yes it
would not be safe to force this feature on some build that is not
actually /usr/src, but is just some program that is using /usr/share/mk.
 So this on-by-default feature would only apply to src builds.  We have
the power to ensure features are limited to in-tree /usr/src builds.
