I had shown an actual message example produced when using #f.  It is
what I want (it just mentions the variable is deprecated, and doesn't
mention a replacement -- there are none in this case).  For a quick
reference, this is how 'warn-about-deprecation' is defined:

--8<---------------cut here---------------start------------->8---
(define* (warn-about-deprecation variable properties
                                 #:key replacement)
  (let ((location (and properties (source-properties->location properties))))
    (if replacement
        (warning location (G_ "'~a' is deprecated, use '~a' instead~%")
                 variable replacement)
        (warning location (G_ "'~a' is deprecated~%")
                 variable))))
--8<---------------cut here---------------end--------------->8---

So I prefer my version.  If you still think the produced message is
weird, I'll need a bit more explanation to understand why you think so
:-).

Maxim
