So what ? I perfectly know that there are a lot of diacritics with cc of 0. It's DEFINITELY NOT me that contested that on this list (and I already posted a reply to someone that pretended to me that this was a contradiction). So you're probably making a false assumption here, as I have NEVER said the opposite. And those 857 combining marks are definitely not a problm for the generality of double diacritics. You can use them with EVEN LESS problems, if the base grapheme clusters ever contain any combination of those combining characters with combining class 0.
