When the service was founded in the 1990's the children they were seeing were probably 90% male and with gender dysphoria of the intractable kind (appearing at around aged 4, and enduring through puberty).
Now there will be a large number of female patients who showed no sign of gender dysphoria before their teenage years, and whose parents were dumbfounded at their sudden announcement.
I think it is appallingly arrogant to assume that nothing in the clinic's approach needs to change, or be re-thought in the light of a new kind of presentation of gender dysphoria.
