实现接口在运行时有什么好处？

Question

我正在尝试了解TVirtualInterface类.

{$APPTYPE CONSOLE}

uses
  SysUtils, Rtti;

type
  ISpecificInterface = interface(IInvokable)
    ['{281D8B97-397E-430A-895A-9CA4E1F5FB5F}']
    procedure SpecificProcedure;
  end;

procedure AProcedure(Method: TRttiMethod; const Args: TArray<TValue>;
  out Result: TValue);
begin
  Writeln(Method.ToString);
end;

var
  ISpecificInterfaceInstance: ISpecificInterface;

begin
  ISpecificInterfaceInstance := TVirtualInterface.Create
    (TypeInfo(ISpecificInterface), AProcedure) as ISpecificInterface;

  ISpecificInterfaceInstance.SpecificProcedure;

end. // TVirtualInterface ref. counter is decremented

在运行时实现接口有什么好处？

空间的用途是什么？
