It does support Field options about protobuf

[hultqvist]

The fields options "access", "generate"... are not the same type of field options as the protobuf field options. They are other type of options for fields used during code generation.

I'll have to look into the protobuf field options before I can see what they are supposed to do. Though I don't think this implementation supports much of them.

It's unclear what you need in your report.
The warnings should probably be addressed but actually implementing the feature might not have that high priority.
If you intend to use custom field options, what would your final use of it be?

As I am a mobile game programmer, I want to check value automatic using custom options...

Ex:
extend google.protobuf.FieldOptions {
optional int32 minValue = 50001;
optional int32 maxValue = 50002;
}

message MyMessage {
optional int32 rate = 1 [(minValue) = 0, (maxValue) = 100];
}

This would be a new feature.

I assume you would implement your own range check but would like to have the edge values in the generated c# code.
