Given that I'd frown upon having two types with identical structure I'd say
this is could be harmfull if swallowed. Thoguh it might find use in
refactoring and maintaining backward compatibility. It does setup an
object dependency which is the only visible difference from just copy the
type definition into the CREATE TABLE. But I'd say if you want a table
with said structure you should plan on droppign the original type after
you've altered all references to it to point to the new implicit type
created with the table.
