The bad construction is the typical half-assery that homeowners expect to be able to get away with. Sure somebody who's frame of reference floats in the sea of flies through the air will probably not take much issue with it but for everyone else it kind of sucks to have to consider where moisture will go and break out the rotary hammer every time you wanna do something. Underground is basically hard mode and it kind of sucks to play on hard mode when everyone else is on easy mode.
