I feel that duplicate-line and duplicate-region should be separate
commands for the sake of semantics.

May be that we implement duplicate-region as more generic and
duplicate-line as a wrapper around it and just pass the line as
argument. If we do that then users are not required to bind two separate
keys for these. Binding with the generic command will serve the
purpose. And users who prefer to call using M-x can still have the right
semantics.
