For filtering, why toggle instead of cycle, or
completion-choose a sort order? I.e., why allow
for only two choices?

Are you sure they raise an error?
(defun foo (&optional beg end)
(interactive "r")
(message "FOO"))
I also think it's misleading to base filtering on
an `interactive' form that uses a string. That's
inherently fragile/limiting. It won't apply to a
form that evaluates a sexp to provide the args.
The resulting incoherence will confuse users.

Same problem. Relying on a string arg to `interactive'
is not a great idea, I think.

I mentioned that I defined that long ago. But I'll
also mention that `describe-function' with a prefix
arg already gives you that behavior. Oops! Nope,
that too is something I defined long ago in
`help-fns+.el'.
Similarly, I defined `describe-option', and a prefix
arg to (my definition of) `describe-variable' limits
choices to user options (like `describe-option').
