Wall Lights, Wall Power Nodes, Wall Thermal Regulators

I feel like it should be possible to place these items against the wall overlapping at least some other objects, like a light above the bed in a room, or a thermal regulator  above a grow bed, or a power regulator above a gas scrubber. As it is, right now it uses up the same space as a lamp, a standard thermal regulator, or a power node. The only advantage is that your crew can walk past it. (You also can't put objects over in-floor power nodes, so a similar problem.)

Still, love the game, and really enjoying my emergent stories! Keep up the good work!
