Sentry is building a new metrics product: getsentry/sentry#58584

Note: We need to be clear that the API itself would be preview, perhaps through xml docs.

Testing / Dogfooding in .NET

Would be great to dogfood this through Symbol Collector which today uses StatsD and emits metrics

The mobile app also has some metrics but it just dumps the Extra on events (can see it anywhere other than individual events).
