This has been declared obsolete for a decade now.

    * eval.c (Fcalled_interactively_p): Add `kind' argument.
    * subr.el (interactive-p): Mark obsolete.

It has been discussed before:

Yet once we obsolete something, there surely has to come a point when we
can finally delete it.

Emacs is already extremely conservative when it comes to dropping
backwards support.  AFAICT, we generally don't delete anything until
five major releases after it was first obsoleted.
