Well, what if someone who lives as a man, but is biologically female, gets pregnant? They have a right to have a clean and private room to pump when they return to work after their maternity leave, just as any other biological female. The challenge is, their "mothers' rooms" are normally 4 chairs in a large room with individual privacy curtains. To avoid any potential issues from someone not feeling comfortable with being in that vulnerable position and someone who looks like a man walking in, they have put one of those 4 seats in a fully-enclosed room with it's own door. Yep.
