Change all of these people to male and you still have the same problem. It is just nitpicking to come up with very specific circumstances where it may come in handy.

Why don’t we create pronouns based upon hair color instead? Dhe for dark haired people, rhe for redheaded, lhe for light haired.

That way if we talk about the Spice Girls, you know who I mean when I say “rhe had the best voice”

Same logic.
