There will be many people who would love to see this happen, but even the current UK puberty blocker ban seems to be very tenuous and maybe even illegal. Who knows what they will try and do, but they have to be lawful.
If they attempt to ban further medications in the UK aside from puberty blocker medications, then what they are actually doing is banning care, and this is not the right avenue to do that. They must act in the best interests of trans people and the public, and they must make sure any risk assessment is robust.
