This all sounds great but if it's a question of priorities I would like
to see more on getting the OT features complete and being able to drop
FT support - so that means CFF and everything else. That's where the
real speed increase is; if OT is not a complete replacement for FT, we
can't use it yet, no matter how fast it is...
