Yes, as I said there has been no updates on guidance that changes any mechanism that has been in place since 2010. Much less a change of law, so things will continue more or less as they have done since 2010.
The law that a blanket ban is unlawful, and must take place on a case-by-case basis, is still inline with no GRC or SRS required to be covered in the first place.
The requirements to be covered in the first place by gender re-assignment P.C. is irrelevant to triggering exemptions, and can not be triggered on lack of GRC or SRS alone, there must be a deeper reasoning, neither will discomfort meet that criteria.
As far as the guidance being a grey area as suggested by women and equalities, I already covered this when I said above, it is almost entirely unenforceable, and unless something that is legal now, becomes explicitly against the law, the discussion is almost entirely a thought exercise with no practical application.
As such, there has been virtually no problems with the current system, the idea there is any kind of legal justification or mandate to roll back equality laws and stipulate obstacles trans women must pass to enter these spaces, and then to pay for some sort of policing at the point of entrance of every such space, is fantasy.
