I just got a reply from Redshift. From Houdini write a vertex color attribute from the motiondata - it could be called Vel or whatever. It imports into Maya as a Color Set which name needs to be entered in the Alembic objects Mesh Controls Motion Vector Color Set, ie. write Vel in that frame - no dropdown with choices, but that's Maya for you.
It seems the Houdini motion data values are per second, so we needed to divide the frame duration by 25 (25fps) to get realistic motionblur. One would expect all this to be transparent to the user in 2018 but hey, it seems everybody gave up on making UI's accessible and cram as much tech crap as possible in instead.
