There is a lot happening in Spain around this at the moment. There has been zero discussion, and it is being slipped through with other more benign measures. Talking to older women here who lived through Francos era, they believe that separate facilities for women take us back to that time, so they won’t see the problems with self ID. Trans males are even winning prizes for just existing. But in small towns most facilities remain single sex at the moment which is a relief!
