bas accepted D293516: Bug 1942862 - Update telemetry alerting docs with latest information. r?aglavic.
In general this looks pretty good to me! I wonder if it's worth adding some documentation that this is kind of an open beta, and that we are actively looking for feedback and criticism of the system. I want us to move forward with this, but I also want to acknowledge this is far from perfect.

This seems strictly better to be. I didn't know this API, pretty neat! (I wonder if it was available already for us when we first wrote this code)
