There are many things in Lisp that users may not understand initially
and so may get wrong.  I don't think that's necessarily a good reason
to keep something out of the language.  (And if it were, there are
parts of CLOS, SETF, and packages that we would want clean out.)

BTW, Pop11 allows user-specified test and hash (key transform)
functions.
