 Below is a checklist of things to be mindful of when implementing a new instrumentation or working on a specific instrumentation. It is one of our goals as a community to keep the implementation specific details of instrumentations as similar across the board as possible for ease of testing and feature parity. It is also good to abstract as much common functionality as possible.

+## 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.
