I'm a bit afraid of the complexity of the dynamic allocation of the
overflow entry. I agree that adding a limitation to 8 combining
codepoints brings static limitation, but conversely there have been
vulnerabilities found due to unbound combining codepoints management,
and for easier adoption, the protocol should be quite simple.
