It would be nice if this error message appended a hint like:

    You can remove the package anyway with --force.

In fact maybe that's sufficient, don't really need a new `replace' subcommand.

Even with a new `replace', the hint would still be handy (and should
also mention `replace'?) because folks will probably first try to do
what Asumu did?
