What do you mean with local version? Your examples are installed
versions, which are pinned with release a=now, compare the output
of apt-cache policy.

No, it explicitly says it does not find the package pin, so that's not
working there either. There seems to be a bug somewhere that causes it
to pick 2.8-1 then, and that's fixed in stretch.

Yay, everything working. So I guess the question is more if /var/lib/dpkg/status
should match origin "" or not.

Well, that's expected, and not really helpful, there are about 2 year
of changes between them.
