I am wondering why many comments for messages (e.g. Update*Request, List*Request), enums (e.g. enum NvmeMultipath) and fields(e.g. parent, page_size) are missed? AIP-192 says that

... public comments must be included over every component (service, method, message, field, enum, and enum value) ...

opicommon.proto file is also missed
