Hey Dude, don't know which procedures your " independant preferred receiver" of you the "independant service provider" (I hesitate to use the word employer) is using but I have never seen any of yours messing with flaps when they have been de-icing around me, and certainly the only mention of flaps we have is to consider large accumulations of slush/crud when deciding to retract (or not) after landing, and to delay deploying them until after de-icing (or approaching departure runway if taxi-way severely contaminated.)
Cycling horizontal stab is another thing, but it seems with the new procedure (which we have adopted) that will now be a thing of the past.
