The ability to protect / unprotect objects so that you do not accidentally dismantle them while trying to get a pipe off the wall. Similar to plants you could make it so that you have to hold down C to clear those protected objects. Ideally if a wall or frame being removed could cause explosive decompression to make it a bit easier to not dismantle it accidentally or maybe if it is in a "finished" like the frame with the plastic sheet added.

A switch in the wrench? I'm not sure why we are using a wrench for walls in first place, but stationeer's wrench visibly looks like it can be regulated, so why not let player set wrench into a position that is pipe-only?
