Using a oneof that supports basic and full ast version -
We may not have to change the protobuf defintion if we use the oneof?

 message Selector {
  oneof ver {
    // Basic version is what we will support in phase 1
    Basic basic = 1;
    // Based on requirements, we can support full AST (The alternative method suggested by Mandar)
    FullAst fullast = 2
  }
}


message Basic {
  repeated MatchExpr expr = 1
}

message MatchExpr {
  map <str, str> match = 1
}
