 ## Releasing dev version of new packages to claim namespace
 
 When a contribution introduces a new package, in order to mitigate name-squatting incidents, release the current development version of the new package under the `opentelemetry` user to simply claim the namespace. This should be done shortly after the PR that introduced this package has been merged into `main`.
