I don't see that at all here in my emacs24:

 (progn
   (defface a nil "")
   (defface b nil "")
   (set-face-attribute  'b nil :foreground "yellow")
   (set-face-attribute 'a nil :inherit 'b)
   (set-face-foreground 'a (face-foreground 'default))
   ;; let's chase how 'a would render:
   (let
       ((init (face-attribute 'a :foreground nil t))
        final)
        (set-face-foreground 'default "pink")
        (setq final (face-attribute 'a :foreground nil t))
        (message "%S %S" init final)))

"\"white\" \"white\""
Per your assertion, the message should have been: white, pink.

Also, your point seems to be: We shouldn't allow nil (to clear
inheritances) for :fg and :bg (unlike for other faces) because: "*we only
allow strings*". I don't get that logic.
