Should metrics be incorporated? Something along the lines of https://github.com/martinothamar/Mediator/issues/57

I'm going to have a look to see if that can be included in 3.x as well, if we do that as opt-in based on configuration

We’ve been using this internally on our team for a while, and today I published it publicly: Neovortex.Mediator.OpenTelemetry .

If you’re interested, we could collaborate to bring it into the Mediator ecosystem—either as a separate package under the Mediator namespace or integrated internally ( we can also consider any change that team wants) .

One important consideration is that most people probably wouldn’t want to pull in the full OpenTelemetry dependencies just for a small project. It would make sense to keep it under the Mediator namespace, but as a separate package altogether.
