@rodaine Hi, I notice the [pr](https://github.com/envoyproxy/protoc-gen-validate/pull/537) has been merged into 0.6.3. but this issue(generating X* for optional field) still exits. Please help to take a look.
@gopkg-dev could like to share how to use your pr? Is there any plan to merge it in master?
