Please don't top post.

Maybe you could have both implementations available? That way a user
could decide to do

struct point : BOOST_NON_DERIVABLE { /* whatever */ };


class Foo : public Bar, BOOST_NON_DERIVABLE_MI { /* whatever */ };

Not the prettiest, and the first example is not immune to subsequent
design changes, but that could be mentioned in the docs...

The best solution would obviously be a single one that works correctly
in all situations. Good luck!
