I would expect that to be data only additions, I would not expect that
to be adding new code.

It would be much better to not have to watch stable constantly like we
currently do - we're seeing people report breakage often enough to be a
concern as things are, we don't need to be trying to pile extra stuff in
there because there's some keywords in a changelog or whatever.  The
testing coverage for drivers is weak, increasing the change rate puts
more stress on that.
