Ok, fantastic, but... what about a direct contact test? What if someone sets a foot there?

With nearly 800 gallons a minute through this single drain, the dye is barely effected only 11 inches away. Drains are necessary when overflows are insufficient to make up required water turnover on pools. Drains are also useful for special self-maintenance systems like what are found infloor cleaning systems.

All national Public and residential ANSI standards require that the skimmer or overflow handle 100% of the turnover rate. The inlets are what move the water - not the suction.
