Given the weather conditions we see in places like Texas some days, it almost feels like roofs/domes are going to become mandatory as we get older. Most of the warmer climate cities were smart enough to build domes/roofs like in Arizona, Houston, Miami, the Rangers new park, i believe Tampa is also building a roof with their new park. I'm sure the A's will build one if their dumbass boondoggle in Vegas ever actually comes to fruition.
The only place where i think would bother me is in the context of some football teams. The Yankees playing with a roof wouldn't bother me nearly as much as say, the allure of Green Bay's mythical frozen tundra suddenly not being a thing anymore.
