Hi, I haven't been able to find any documentation that explicitly states whether the wire (binary) format of Protobuf v2 messages are compatible with protobuf messages generated with v3 (using `syntax=proto2`). The only documentation seems to mention API differences between the two library versions.
We use protobuf-java and would like to transition from PB v2->v3, but only for new message types. We would like systems that use protobuf-java v2 and protoc v2 generated messages to be able to communicate with systems using protobuf-java v3 and protoc v3 generated messages (and vice versa). It stands to reason that messages that use `syntax=proto3` are not guaranteed to work in this fashion, but I'm curious about messages marked as proto2.
