In programming modes, if you need to declare a bunch of variables, you
may duplicate the current line several times and then proceed to rename
them.  I see the proposed new command may be useful in that scenario.

Also, why not name the command `duplicate-line'? I think it's a more
descriptive name and more discoverable via apropos (along with
`delete-duplicate-lines', for example).

This has been a hot topic in Q&A sites:
