It is working for me in Emacs 27, and it was working for me at the time
when I wrote it (both byte-compiled and interpreted).

I test by evaluating this in "emacs -Q":

    (defmacro future-interactive (arg-descriptor &rest modes)
      "Use the correct `interactive' form for any Emacs version.

    This is a forward compatibility macro that allows code providing
    the third argument to `interactive' (added in Emacs 28) to
    continue working on old versions of Emacs.

    To use it, replace `interactive' with `future-interactive'."
      (if (< emacs-major-version 28)
          `(interactive ,arg-descriptor)
        `(interactive ,arg-descriptor ,@modes)))

    (defun foo (arg)
      (future-interactive "P" fundamental-mode)
      (message "P was %s" arg))

And then I say `M-x foo RET'.  If `footnote-mode' is activated, the
macro did not work as expected, otherwise it did.

Bisecting points to c1ef7adeb649aa as the first commit that broke it.

Are you seeing the same thing?
