The fundamental unit for protobufs (across all serialization and presentation formats, including JSON) is a message.
The semantics of the general JSON format do not map to protobuf semantics very well, but the proto3 language guide has a section on the JSON structures that can interoperate with protobufs: https://developers.google.com/protocol-buffers/docs/proto3#json The impetus for JSON interop is for servers which can understand either JSON- or wire-formatted requests, so a top-level list would pretty fundamentally break semantics. Given that pitfall, it's pretty unlikely that we would add support for anything other than a top-level message. The example you gave is how I would recommend representing "just" a list.
