Because it didn't work.
(defvar foo-var 0)
(defmacro foo-mac ()
'(setq foo-var (1+ foo-var)))
(define-obsolete-function-alias 'old-mac #'foo-mac "24.4")
(defun foo-fails ()
(old-mac))
(defun foo-works ()
(foo-mac))
Compile:
foo.el:13:4:Warning: the function `foo-mac' is not known to be defined.
Load compiled version:
(foo-fails) ; -> (invalid-function old-mac)
Also, neither version warns that old-mac is obsolete.
I see now that
(eval-and-compile
(define-obsolete-function-alias 'old-mac #'foo-mac "24.4"))
works. So maybe that should happen automatically at top-level.
