Yes, that's fair enough.
To be clear, I don't think the guidance that was supposed to be issued by now should be striving to be a comprehensive guide to all things gender-related.
I think that's too ambitious and unrealistic given where we are, and I think this huge question about social transition, while a very important long-term question, is not appropriate to be shoe-horned into urgent guidance that schools need right now to deal with actual issues on the ground.
Since the government doesn't have clarity on where they stand legally on social transition (which they obviously won't do as it would require more clinical research and more clarity around what gender identity is, and if the NHS don't know what to do for the best yet, why would the government know any better?, and so on), then they at least need to produce some interim guidance on the issues they can currently guide schools on, such as single-sex spaces, how to deal with gender critical views, and so on.
I think delaying the guidance until legal clarity on the whole issue is achieved will mean that no guidance ever materialises, and it will end up being settled through employment tribunals and discrimination cases against individual schools/councils anyway, as schools are inevitability going to be forced by circumstance to make the difficult decisions the government is still grappling with, and most schools won't be able to keep everyone happy in making those decisions (and yes, I agree that most people won't take legal action and will simply move on to different jobs or schools through necessity).
While the government can hold off on issuing guidance, the schools can't hold off on making operational decisions on these issues involving actual pupils. They can't just close schools until they have appropriate guidance, and a single child, for example, can't be both prohibited from using the toilets of the opposite sex and allowed to use them, so there will be no option for schools to sit on the fence the way the government is. Schools are going to have to continue having a stab at getting all of this right, regardless of whether or not the government intends to keeps shifting the scope of this fabled guidance until they run out the clock.
