The TC discussed this during the Mar. 13th, 2024 meeting:

  1. There is only one blocking issue (more details can be found from Tracking: Exemplar Specification - Stabilization #3756), @jack-berg is working on it Clarify that exemplar reservoir default may change in a minor version #3943.
  2. After PR Clarify that exemplar reservoir default may change in a minor version #3943 is merged, we should be ready to move this PR forward. We're targeting mid Apr. for the Metrics Exemplar spec to be marked Stable (spec release will happen early May).
