The proto files can be consumed as GIT submodule or copied over and built directly in the consumer project.
The compiled files are published to central repositories (Maven, NPM...) from OpenTelemetry client libraries.

In some cases we are trying to experiment with different features. In this case we recommend using an "experimental" sub-directory instead of adding them to any protocol version. These protocols should not be used, except for development/testing purposes.
Another review must be conducted for experimental protocols to join the main project.
