In a more general setting, I have a big beef with removing software just because it's beeen written a few years ago, and there has been no recent new version.
So what ? not everything has huge security implications. Not everything needs to be updated every two days to be useful. Both kguitar and taxipilot only require kde/libs3, not anything else from kde3. And they still work. More importantly, I see *no alternatives to these ports* in our tree. Show me another "space taxi" clone. Give me some guitar-pro reader that's in the ports tree (and preferably not a huge pile of compiled java) then we'll talk.
