This behaviour is not limitted to font related attributes.

If the arg FRAME is nil, set-face-attribute changes
attributes on all frames plus the default for new frames

But customize-face changes only the attributes of existing
frames.

(face-attribute 'default :background nil) => "#ffffff"
(face-attribute 'default :background t) => unspecified

(set-face-attribute 'default nil :background "gray")

(face-attribute 'default :background nil) => "gray"
(face-attribute 'default :background t) => "gray"

(customize-face 'default) ;; set :background back to "#ffffff"

(face-attribute 'default :background nil) => "#ffffff"
(face-attribute 'default :background t) => "gray"
