Actually this kind of summary is misleading (and I understand
you're just following what others did before, i.e. this is not a
problem just here): For it to be meaningful, one would need to
know whether reviews/acks are in place by all necessary
maintainers. But of course the summary helps in drawing
attention to things completely un-reviewed/un-acked.

Perhaps one could use upper case letters to indicate full
maintainer review/ack state?
