35 years of experience suggest it's not needed (thank god).
It's quite easy to instead do something like

    (defun foo (..)
      (call foo-function ..))

and then use a buffer-local setting for `foo-function` to get the same result.

35 years of experience suggest it's not needed (thank god).
Also, I think this could lead to quite unexpected semantics.
