DE is not at all an intrinsic part of "the" deep litter method. (There really is no "the" - there's a whole range of different ways of doing things, each with their unique benefits and disadvantages).
Dust, especially mineral dust which includes food-grade DE, is not good for the respiratory system, not for mammals nor birds. While a coop is unavoidably going to be a bit dustier than, like, your living room, you still need to do everything practical to keep the dust levels down. WHich includes not whooshing DE around like mad or in unreasonable, dust-causing quantities.
YOu do not need DE to combat smells or dampness or flies if you have adequate ventilation and sanitation.
And I know of no reason to believe that lots of DE is any more effective as a mite/lice preventative than just a *little*, strategically-deployed DE (which, itself, is not *proven* to do any good as a parasite preventative -- although it does seem to me like it helps, thus I do use it in that way myself)
