Are you planning on supporting importing the proto .bin format that stores file descriptors? This is the output of the proto compiler and would make it easier to provide a full transitive closure of deps for people who have complex build phases. You could also make a bazel rule set for exposing `bazel run //service/proto:postman` with default configs.

Not sure about the .bin format yet but will check with my team. The immediate next step is multi file support.

The nice part of the `.bin` format is you don't need to do anything to support multiple files or cross deps. The build system packages all of the files/messages/services into a single file for you to load.
