All women have wanted for ages is that the correct boundaries be put in place.
Time will tell whether the boundaries that end up in place are indeed correct, though. Far too often, it was the Ladies loos that (as well as doubling as the Disabled loo and the baby-chasing one) was designated 'gender-neutral', so men could use the Ladies as well as the Gents, and women had nowhere to call our own. That was not, IMO, the 'correct' boundary.
If transpeople adhere to the spirit of the ruling, and use the facilities designed for their biological sex, not their psychological 'gender' then yes, I see no reason why relationships should not improve. Personally, I have never had a bad relationship with a transwoman in the first place. I just want women and girls to feel safe, to have dignity and privacy, and for statistics to properly represent trends in society and health concerns that affect the sexes differently. I would also like to see female shortlists being for women, and for sport to be fair.
