I believe it is a consequence of Trump's push to enforcing border controls with the existing legislation. It requires illegal immigrants to be sent to federal jail until their case is looked at, and kids can't legally go with you to jail (obviously).
If they want to enforce the border they will need to put in place a less inhuman/bad looking system. In the past presumably the way round this was to not enforce the legislation - let people in?
