I know of people who get cranky when the sun rises. But in fact the problem
you're describing is largely the result of a vast difference between the
design philosophy with which I originally wrote the client and the design
philosophy of the ifup and ifdown scripts.
In the context of those scripts, of course it's a horrible botch that the
command line doesn't override the configuration file, but it was never my
intention that the DHCP client should be started and stopped on a
per-interface basis, nor that there ever be more than one instance of it
running at a time anyway.
I say this not to indicate "so it's not a bug," but merely to point out that
there's a reason why it's that way - it's not an accident.
BTW, since you're here, do you have any clue why the kernel won't receive
broadcasts to 255.255.255.255 when the interface has a zero IP address?
