I'm 6'3" but have a longer upper body and relatively shorter legs to get my height. My kid is 6 ft tall and has 1 inch longer legs. If I was more proportional, I'd likely be 6'5" with longer legs. So for a bike to be comfortable when riding, I got taller frames, and adjusted peddling with crank length and seat position. That way the head tube to seat post dimension was correct and my riding was more comfortable. I stand much less then I ride, so I make the fit work for riding and track stand as much as possible. If I have to I unhook and lean to one side. I can straddle the tube but it's close and not worth the risk for a basic stop. In an emergency or a crash you may hit anything on the bike down there anyway.
Someday I'll join this century and buy a newer bike without as much of a horizontal top tube; then not care at all.
