A TDataModule without resource makes no sense. At runtime instead of a
TDataModule you can use any TComponent.
Same for TFrame. At runtime you can use a TPanel instead.
That's why it makes sense to raise an exception if a TFrame/TDataModule is
created without a resource.
OTOH a form without resource makes sense and is often done.

There are more differences than similarities between TForm and TDataModule. And
TForm is older than TDataModule.
