Not blocking, but I would suggest extending the documentation (for both contributors and users) to explicitly describe the expectations for metric quality, usefulness, and production experience at each level. Similar to the Kubernetes feature lifecycle, metric levels like Alpha, Beta, and GA should reflect whether a metric has been validated in a real-world production environment.

For me that would be:

• Alpha: New metrics with minimal or no production experience. There is no expectation for users to monitor them yet, as they may belong to Alpha features or haven't yet proven their long-term value. Due to the lack of production feedback, there is a high probability these metrics will change or be removed entirely.
• Beta: Metrics that have been validated in production and deemed useful. While not yet "critical," it is recommended that users begin monitoring them. The expectation is that metrics for GA features and critical metrics for Beta features eventually graduate to this level. While less likely than Alpha, these metrics might still change if they are tightly coupled to internal implementation details..
• GA: Crucial metrics covering core Kubernetes features that are expected to change very rarely, if ever. Users should prioritize monitoring these metrics to understand the fundamental health and performance of their clusters. Owned by SIGs.

I think thats a great addition. Included your suggestion in description for each level. Thanks!!
