OK, no, the source [1] has this part:

    (defun byte-compile-save-excursion (form)
      (if (and (eq 'set-buffer (car-safe (car-safe (cdr form))))
               (byte-compile-warning-enabled-p 'suspicious))
          (byte-compile-warn
           "Use `with-current-buffer' rather than save-excursion+set-buffer"))
      (byte-compile-out 'byte-save-excursion 0)
      (byte-compile-body-do-effect (cdr form))
      (byte-compile-out 'byte-unbind 1))

Well, hell, worth a shot...

BTW, bytecomp.el itself relies heavily on
`with-current-buffer' so in a way it makes sense it
suggests it :)
