I agree.

When help argument highlighting was introduced, there was some
resistance to adding more configuration options (surely because we
were in the long road to Emacs 22 and everybody was tired and wanting
to speed things up), and the argument was put forward (by Richard,
IIRC) that variables were just one option for the user to customize
his Emacs environment, redefining functions being another.

I was unconvinced then and I'm still unconvinced now. Redefining a
standard Emacs function (or advising around it) in your .emacs is not
a good idea; any change in the source of the original function will
catch you off guard.
