Indeed, your assignment is on file.

Thanks for bringing this up.

I looked into the history of this variable, and found that it was
still supported in Emacs 24.5, and was removed during development of
Emacs 25 by this commit:

  commit 0e4857b7d84f958f66e726ed57b824427b272681
  Author: Stefan Monnier <[email-masked]>

      * src/callint.c (Ffuncall_interactively): New function.
      (Qfuncall_interactively): New var.
      (Qcall_interactively): Remove.
      (Fcall_interactively): Use it.
      (syms_of_callint): Defsubr it.
      * lisp/subr.el (internal--funcall-interactively): New.
      (internal--call-interactively): Remove.
      (called-interactively-p): Detect funcall-interactively instead of
      call-interactively.
      * lisp/simple.el (repeat-complex-command): Use funcall-interactively.
      (repeat-complex-command--called-interactively-skip): Remove.

As you see, the commit log doesn't mention the removal of the
variable.  Stefan, was it removed on purpose?  If so, can you tell
why?

Thanks.
