I think we’ve always got reason to be cautious of the outcomes of this exercise of course, and I don’t know the extent to which they will be taking an appropriate range of views, and of course the usual suspects will make their case-
But:
the fact that the scope of this thing is looking at girls only, ie female children (while we are pre self ID and pre extension of GRC to children as the TRA lobby might wish-)
This is really good that there is an exclusive drawing up of the scope to females.
This does give the opportunity- and whether or not it is taken by government remains to be seen- for all the obvious points to be made about the current pornified and gender-rigid, social media- saturated social context for all girls and young women.
It gives the opportunity for the government to observe the radical asymmetry of the drivers and costs for transition for male and female people against a backdrop of deeply ingrained cultural misogyny.
If it was looking at ‘children and young people in general’ then the gender critical concerns could still be put, but the unique burdens affecting girls and women of this phenomenon would be less prominent. There might be more of an ‘even handed’ 
approach taken to the drivers between the sexes which would more easily mask why young girls are in droves presenting for help with this issue, whereas young boys relatively are not.
And absolutely agree with PP they should not ignore the girls self medicating off the internet as the TRA lobby and some sections of the media do. NHS stats are by no means the only measure. And they should look at all young people coming into these services- so include young adults over 18 also.
Personally I would be happy to see a conclusion of this investigation that more psychological support should be provided to these girls and young women and that a watchful waiting type of approach should be put in place.
Providing ‘affirmation’ medically or surgically without extensive prior therapy over time is clearly dangerous. But social contagion and ROGD is a thing, and for some time it would seem likely that demand will continue to rise for these services. At the moment detransioned people are still being marginalised and research into their experiences is reported to be being suppressed.
But that isn’t sustainable over the long term as unfortunately the more children and young people who take the medical and surgical route, the correspondingly greater the numbers of detransitioning people will be, and the greater the numbers of young people for whom the steps of medical and surgical transition that they have taken have not relieved their dysphoria or anxiety or mental health issues or who find medical and surgical changes made have brought in a whole set of new, permanent problems for them. 
Government and public sector in general needs to look at it now because as we know from experiences in health, education and other sectors a lot of the public sector is currently being encouraged to do the work of the TRAs for them, either or both by adopting a rush to ‘affirm’ medically or surgically or mysteriously accepting a very dubious claim by the TRA lobby that normal safeguarding practice which should apply to EVERYONE is somehow ‘transphobic’ when applied to them.
So in the mean time, whether this government exercise is well intentioned or not, let’s try to expose this whole thing to as much sunlight as possible and try to get the facts into the open as far as we can.
Not least about how if normal women and parents try to ask the simple questions that Mordaunt and the government are asking we get threats and intimidation and doxxing and punched to the floor at Speakers’ Corner.
Then it will be harder for the government to reach a santised, one-sided conclusion without that being glaringly obvious to a lot of people that that’s what has gone on.
Sorry that was long.
