No. "Default ignorable" decidedly does *not* mean ignorable
for canonical ordering. Any ccc=0 combining mark, including
CGJ, makes a difference for canonical equivalence.
"Default ignorable" has to do with whether, when otherwise
not supported in rendering, a character should display
with a visible blort or with nothing at all.
