Hardly anyone wants it and it makes no commercial sense to provision a whole bunch of extra bandwidth just to satisfy the Speed Test wishes of a small number at this time.
But if you want it, have a chat to Dan Faulknor (post above). They are an individual I am in regular contact with and respect as an industry peer.
I may advocate for it with the ISP's I work with if there becomes further business demand and/or marketable use cases.
