I guess that's the problem which is not new.

IIUC Org's clustering was only introduced because self-insert-command's
clustering only worked when it was handled by the read-eval-loop, so it
was not done to "avoid" the clustering, but to make it work in more
cases.  So it might be unneeded in Emacs-24.

I don't have it fresh in my memory but if you can post some sample code
showing what you're doing, and how self-insert-command's behavior makes
it difficult, maybe we can make it work better.

Providing it as a variable would be very easy, indeed.
