while checking the v1.1.0-M1-RC1 artifacts, in both pekko-connectors-google-cloud-pub-sub-grpc_2.13-1.1.0-M1-RC1.jar and pekko-connectors-google-cloud-bigquery-storage_2.13-1.1.0-M1-RC1.jar and their 2.12 counterparts, I encountered .proto files in the published jars but not in my locally-built artifacts.
