On top of the obvious foot-in-mouth about the naming (I honestly assume good faith here and suspect it's just really bad wording without talking to people beforehand): I do not understand why at #39c3 toilets are gendered by apparent default. We used to have editions in which the all-gendered toilets were the default and only a few gendered toilets for those who actively prefer them.

Slap stall distribution information and a "whatever, just wash your hands" next to the entrance, and done.
