tl;dr: It's essentially just a humidity-adjusted temperature, like wind chill factor for hot weather. The important figure to know is that a wet-bulb temperature of 35°C / 95°F (equivalent to that temperature at 100% humidity, or higher temperatures with lower humidities) will kill everyone.
This makes me wonder if it is (or will become) economical for cities to use renewable energy to dehumidify the outdoors, and if so whether the yield of water would actually be useful.

Well people will likely first start cooling and lowering the humidity indoors with their ACs. The condensate might be used to feed the household hydroponic systems.
