Pretty sure this is just the results of the fix for bug 1498942 making its way into release. You can see that we went from 25 events of this kind per 1000 usage down to around ~1 from 63 -> 64:

We saw a similar pattern on the beta channel after this landed

:chutten and I had a discussion about this yesterday on mission control irc channel:

I took a look at nightly shutdownkill volumes: https://sql.telemetry.mozilla.org/queries/60652#156515

The first cliff is the build where bug 1498942 landed, so that certainly seems to be the likely culprit.

Non-content-shutdown crash pings are so infrequent on nightly since November that it's tricky to say, but I'm pretty sure they didn't show a similar effect (https://sql.telemetry.mozilla.org/queries/60689/source#156621).  This suggests that the reduction in shutdownkill crashes is almost certainly the cause of the volume cliff.
