"But that usually will create another problem."

Then the test must be: does any particular proposed layer of
indirection solve more intractable and more valuable problems than it
creates, enough more valuable to be worth the cost of implementation?

Still, I concede that it would be "better" to more effectively use the
indirection layer we have (DNS) rather than create another. Better,
but not necessarily achievable.
