That could be one conclusion since it may lead to more desirable outcomes. On the other hand, we generally don’t allow children to undergo other permanent procedures (eg. Nose jobs, tattoos etc.) because children change their minds. It can be argued that medical transition is necessary medical care (eg. like how we give chemo even though it may have permanent long-term effects.)

However, since dysphoria is a psychiatric diagnosis (there’s nothing physical to test like a tumour) we cannot be sure in the same way that treatment is medically necessary. Therefore, I believe that the care providers should have to be extremely sure that the child is not going to detransition before making any medical moves like puberty blockers or HRT. I’m not convinced they can be sure enough or at least that they are being that rigorous (they clearly weren’t here: https://www.bbc.com/news/uk-62335665.)
