Hi,

Just realized while searching for leftovers in this thread that this last
bit of the discussion was still not over.

Agree it doesn't make much sense.

Added it to the blueprint as a future possible enhancement if we feel it's
needed.

I think on the contrary it might be useful for people that are not core
devs to get notifications on build failure.

I don't think it's that important. The only use case I see where it would
change who gets the notification would be when one of us import a patch
we received. Then, it is interesting still to use the author field, as it
means that the notification would be sent to the one who actually wrote
the patch, and not just to the one who merged it. Or maybe we want both of
them to be notified?
