    It makes some sense, but falls short of being really useful as a set of
    goals; or as a definition of the LSM interface.  What are the "needed
    hooks"? Define "need": a trick question because the "need" is, by
    definition, decided by consensus (or so it seems.)  This seems to be the
    primary area for debate.
    
    As far as the idea of "leaving it to the module developer(s):", that is
    currently the situation.  Unfortunately, any module developers building 
    systems that don't fit the current model must do their own patch and
    use the LSM hooks in a "subset" manner or, possibly, just patch the kernel
    completely otherwise.
    
    There are better ways to tackle the "first problem" and still acknowlege
    the "not tackled problems".
    
    Sincerely,
