I can't find any version of Emacs in which C-h C-a runs apropos.
I went back as far as 21.1.

Yes, C-h C-a runs `about-emacs' since Emacs 22.2. Before that, it was
undefined.

As we can see below in the *Messages* output, it actually says:

  For information about GNU Emacs and the GNU system, type C-h C-a.

which is true, but pointless, so the messages was removed recently
and will be gone in Emacs 24.3. http://debbugs.gnu.org/12680

I disagree that the about-emacs screen needs to mention apropos.
