Given this workaround, it's probably not a high priority to add this.
Hmm, what about a seperate @echoifexists or similar command?

The issue is that you need to find a way to keep users from installing
packages they can't uninstall. If you add new commands and they are
used in ports, users with older systems won't have the necessicary
pkg_delete commands to make them work. The current system doens't even
give a graceful way of detecting this condition both in the port and
when the users installs a pkg from the -stable collections online.
Longer term, we need some versioning in the plist and ports, but first
we've got to solve the problem we're stuck with now.

Last I heard, eik was the one working it, but no one has heard from him
in a while. He's been gone long enough that someone else could
certaintly commit to pkg_install given public review.

This would be a really cool feature. Off hand, you'd probably want to
create another dirctory under /var/db to store these records. That
would certaintly be allowed to support such a feature.
