Not a nightmare, no, but it’s definitely a problem that needs solving. As it is you have lines out both doors. If you open both bathrooms to either gender you significantly decrease the efficiency of the “men’s room” since you’re going to have a line of people who can’t use urinals stopping people from getting to the urinals.
You could design facilities to make it work, but our current facilities would be significantly less efficient.
I’m presenting a perfectly valid issue and your answer is to cover your ears and say someone else will figure it out.
