Such advice should be in the docstring for the variable; I don't think
it's really needed in the ChangeLog (where nobody will read it, I hope
-- if they do read it, it probably means it's buggy! ;-)

In fact, I wonder if it wouldn't be best to have the default be
beginning-of-defun-raw.  Being permanent-local should be enough
protection for the default.  (Didn't you sugest that on emacs-devel?)
