Basically this would allow for things like designating specific people that can terraform a specific group parcel. For instance, if there is a chunk of group land, and a couple members want to build a canyon and a bridge. It would be nice to be able to say, "Hey, you can dig a canyon on that plot... but we're safe from any accidental or purposeful gouging of our pain-stakingly arranged terrain over in this other plot."
Another specific permission I can think of off the top of my head is the permission to use the "delete all owner/group/other objects" buttons.
Obviously we wouldn't want this to become severely complex and convoluted, but it seems that a lot of these particular things could be lumped into a "Land maintenence" permission.
Suggestions, alterations, derisions, etc. all welcome.
