I'm starting to think about how to allow for updating SDK configuration. Starting with metrics because traces and logs are a cake walk in comparison. While doing some analysis I realized that MeterSharedState is a silly concept - all of its logic and state can just be held directly on the respective SdkMeter.

This reduces complexity and makes it easier to reason over.

I believe this was a holdover from OC metrics, where (IIRC), you could have more than one meter instance that shared the same state. If we don't need it any more, then 🥂 !
