Also don't forget they're likely to add some code point reordering. Do we
want that too in an alternate scheme? Then is it really that much simpler
than SCSU? (Probably; tables for code point reordering are not complex to
build. But they may take some effort to optimize, so my guess is the
implementation effort may be roughly the same.)
YA
