Apologies for the delay. I tried pinning again on a fresh Stretch VM. It
looks like I confused myself by assuming that all the extra packages to be
installed were from sid as well, whereas -d shows that the vast majority
are coming from stretch/main. Sorry about the confusion, given this
behavior I completely agree that this should be the documented way to get
wireguard before stretch gets released as stable.

The transcript below still shows one additional package being pulled from
sid/main, the dkms package. I find this strange: wireguard-dkms depends on
dkms >=2.1.0.0, stretch has dkms 2.3-2, and sid has dkms 2.3-3. Despite the
negative priority for unstable, apt picks 2.3-3 from sid, even though the
dependency could be satisfied out of stretch. What am I missing?
