define-derived-mode and property lists

Hi, I noticed today that the function `define-derived-mode' doesn't copy the property list of the symbol which refers to the command which starts a mode. I tried LAML (great stuff) and its Emacs mode. I noticed that font-locking didn't work (also the mode is derived from scheme-mode). The reason is that the keywords for font-locking are set in the property list of the command `scheme-mode'. I tried a simple (map-plist #'(lambda (key val) (put 'laml-mode key val)) (object-plist 'scheme-mode)) and everything was fine. So shouldn't `define-derived-mode' run something like that also?
