What type of notifications would you like to track / announce and how?

Our team at ByteBeacon built a simple REST notification service for internal use where we posted updated on a slack channel. We tracked a lot different operations, but it wasn't meant to replace our metrics pipeline. We soon noticed ourselves using this in alerting on critical failures, but the successful posts were good in keeping logs (later used when debugging). We feel we have something in our hands, but want to validate with other dev on how useful this can be for them. Would anyone like to share their experience here?

On top the dev use case: A friend of mine (non tech) saw this and mentioned an announcement platform use case where she can use the same platform and have her society member subscribe to an announcement channel and send notifications about changes in society policies (specially applicable in cover-19 related announcements for localities in lockdown). We're almost done with a beta release for it as well, but feel there are a lot more use cases that can be addressed.
