if you have the technology to get riven boards flat enough to glue
them together you almost certainly have the technology to saw the
board you want out of the log.

Ok, riven boards are to "wavy". But if you saw the trunk into
wedge-shaped boards you would have only true "quartersawn" surfaces,
and could then glue them up to rectangular-sectioned boards, with
minimal losses.
