Quoting from NEWS, we already added the foundation for this:

** The variable `safe-local-eval-forms' specifies a list of forms that
are ok to evaluate when they appear in an `eval' local variables
specification.  Normally Emacs asks for confirmation before evaluating
such a form, but if the form appears in this list, no confirmation is

IIRC, we discussed back then whether to give the user a choice to
automatically add an eval form to that list when prompted to confirm.
But it was rejected/postponed due to lack of interest.

Since safe-local-eval-forms is a defcustom, the feature can probably
be implemented quite easily via suitable custom functions that updates
and saves the value.

BTW, shouldn't safe-local-eval-forms be marked risky ???
