I agree, but

    There are several variables that control how Font Lock mode
    highlights text.  But major modes should not set any of these
    variables directly.  Instead, they should set `font-lock-defaults'
    as a buffer-local variable.  The value assigned to this variable is
    used, if and when Font Lock mode is enabled, to set all the other
    variables.

This will DTRT.
