[Bug]: No error when referencing readonly service object inside non serveice class

[rdulmina]

Description

public type FooObj readonly & distinct service object {
    isolated remote function execute(string aVar, int bVar) returns int;
};

readonly client class FooClass {
    *FooObj;

    isolated remote function execute(string aVar, int bVar) returns int {
        return bVar;
    }
}

Including the service object FooObj inside FooClass does not give any error. If we remove readonly from the FooObj it gives the error invalid object type inclusion: missing 'service' qualifier(s) in the referencing object
