unrelated but noticed when adding transport-grpc

[agoallikmaa]

What are the ramifications of this on configurations of existing deployments? If this is released as a non-major version of exporter-otlp, it would propagate to everyone who uses ^1 constraint for that on next update, breaking their configuration for the next run. Would it perhaps make sense to merge this to 2.x?

It would break for those using the configuration module. But, it's still at version 0.x, and based on a development-stability part of the spec, so breakages are expected at this point. There are no changes to exporter-otlp.
