Is this going to cause problems for messages with optional fields with validations?

generating gofiles with a message like this works just fine now.

message AddEntityEntitlementRequest {
    optional string name= 1 [(validate.rules).string = {
        pattern:   "^[^[0-9]A-Za-z]+( [^[0-9]A-Za-z]+)*$",
        max_bytes: 256,
    }]; /** name */
}

the regex fails when expected and if no value is provided, no error is thrown, since it's marked as optional.

I don't know the ins and outs of generation, especially since that piece comes from the original PR, so I'm not sure what the halo effect is like with this change.
