Two commands are not necessarily more convenient than one command.
There is also the advantage of not disturbing the kill ring.
(And for rectangular regions the benefit of a duplication command is even 
greater.)

There does not seem to be any significant benefit from omitting the 
region-sensitive behaviour.
We could add `duplicate-dwim` as a separate command but then there would be no 
reason to use the neutered variant, would there?
