That's actually supported by the BASE table's centerline baseline already. Let me find it in CSS verbo.

Humm. Maybe not. IMO it should work though.

I spoke to @dberlow today and he mentioned that the v metrics in OpenType are static font technology, and with a VF, across the design space, the v metrics are mostly inappropriate. Is MVAR a way to make different sets of metrics appropriate to eg each optical size, weight and width?

Adjusting v metrics across the designspace is one of the main reasons for the existence of MVAR. See this tweet for an animation of variable sxHeight and yStrikeoutPosition in Source Serif 4.
