WHat's next? Equi-grids for the kitchen disposal, dishwasher, and whirlpool tub in the bath? Heck, let's do the whole yard, in case someone later installs a birdbath.
Heaven forbid someone decide to shift the package unit over to the other side of the patio, or set it up in the garage in the winter. After all, they get filled with a garden hose, and can go anywhere.
I'll tell you where this will all lead. It will lead to a world where Billy-bob 'hillbilly engineers' some bit of kludge that is truly dangerous, everyone makes an occupation out of avoiding city hall at all costs, and every street will have some bitter harridan peering through fence slats hoping to cause trouble for the neighbors.
