Avenger,
Correct JD, BA modified their Tristars in 1981 for improved blending and gust control, modern jets, B737, Airbus etc, do not suffer this problem to the same degree.
LAF (Load Alleviation Function) on the A320.

There shouldn't be any anti icing fluid on the flaps because the de / anti -icing is performed with the flaps up
Not necessarily. I know of one A330 operator who sets flaps to a T/O position before de-icing. I assume it's just in case there is any accumulated snow/slush attached to the structure from a previous landing. But someone will enlighten us I'm sure.
