From a TH8 perspective it adds to my base being more symmetric if I can have 4 spaces where hidden buildings pop up, (currently 3 teslas) and people using air attacks easily know where to attack from. It just makes sense for it to be a building that pops up out of the ground in stead of showing by default, it even takes the same amount of space as a tesla.
This may take some rebalancing for it first, but I think it would be worth it.
