Part of me thinks they shouldn't be allowed to 'limit' the scope of a midwife to attend even high-risk homebirths as long as the mother is informed that it is considered such - after all - a women can theoretically refuse any intervention at a hospital anyway? So why insist that she be put in an environment she doesn't want to be in in the first place just so that it's easier to offer things/impose timelines she'll likely want to refuse/buck anyway? Seems far safer to just let her try at home, fully informed and attended by a professional, than having a woman attempting freebirth or birthing with a midwife working illegally who would then be far more reluctant to transfer to hospital than someone allowed legally to attempt it at home.
