It has nothing to do with your PR, but I just completely hate this design decision in protobuf. What a disaster for authors and readers of protobuf.

I’m tempted to say we create a new thing, Syntax2 or something, that offers these things, and keep Syntax as-is? Making a big binary-incompatible change to wire-runtime has a potentially large user impact?
(Why is Syntax in the runtime API?)

Because it's passed as a parameter to adapters
expect abstract class ProtoAdapter<E>(
fieldEncoding: FieldEncoding,
type: KClass<*>?,
typeUrl: String?,
syntax: Syntax,
identity: E? = null,
sourceFile: String? = null,
) {| // Created for backward capability with when Syntax used to be an enum. | ||
| fun name(): String { | ||
| return when (this) { | ||
| // TODO(Benoit) Edition needs to return something like `Edition(<value>)`. |

Yeah, yuck. Anything calling this might not be able to parse it later

defaulting to proto2 behavior, which is kinda wrong.
The way we break the world for Java callers is very sad...
Maybe we could just manually increate the enum values one bye one each year...
