Ah, excuse me, "binary compatibility" is wrong word. I wanted to
ask the compatibility from current "sfnt/LWFN driver" to future
"fbit/NFNT/sfnt/LWFN driver". Your reply about NFNT is enoughly
suggestive.

Yes, thank you for pointing out! NFNT resources are separated
for each sizes, just aslike strike of sbit. Could I know more
about WINFNT encoding issue in ft-devel archive? I found a note
of moving from strikes to faces in docs/CHANGES freetype-2.1.4
to 2.1.5. My initial fix of ftmac.c will ignore the number of
NFNT resource.
