Proto3 introduced the optional syntax to support field presence tracking in release 3.12.0. We need to add support in our grpc protoc plugin.

See this doc for more details. Basically we need to add a function GetSupportedFeatures() to our grpc protoc plugin to mark our compliance.

Please plan to do this in the next release. If not, please let me know. Thanks!

Do we want the protoc flag --experimental_allow_proto3_optional on by default?

Yes please turn it on by default. At first I thought the flag only applies to protoc. Looks like it applies to the plugin as well (i.e. will fail the plugin if .proto has the new syntax and the flag is not passed in)? Then yes we do want to turn on the flag by default. Thanks!
