Which doesn't bring any real additional benefits, unless you want to 
prevent yourself from ever doing 'dpkg -i systemd*.deb'.

Pinning supports blobs and regexes, so it should be quite easy to pin a 
number of related packages with just one or few patterns. In case of 
systemd this is not even necessary, because the other related packages 
have Depends: systemd, and apt will refuse to install those as well.
