See a thread here called “Char-folding: how can we implement matching multiple characters as a single "thing"?”.
In summary, char folding was generating regexps that were too long for Emacs to handle.
The best solution we reached was to make char folding dumber, so that the resulting regexps wouldn't grow exponentially.
The C-level implementations of char folding that have been discussed wouldn't have this problem because they wouldn't need regexps.
Even with the current solution, char folding can still produce too long regexps if the input string is very long (which it handles by falling back on regular search).
A second disadvantage is that you can't do char folding for regexp searches (though I can't tell how common that would be).
Yes, I read that part of the thread. But thanks for the reminder.
