Taking this a bit further, I think ideally the subject would identify
whether or not the patch was selected by a bot, and it shouldn't get
backported to stable unless either the author or maintainer acks the patch,
or there is a tested-by from somebody reporting that it fixes a bug on
that stable tree that has actually been seen without it.

On the flip side, it means that the default response (silence) stops the
patches getting into stable, which isn't ideal for Greg. Thoughts?
