What are some geometric applications of integral p-adic Hodge theory (as opposed to rational p-adic Hodge theory)? I am aware of certain applications to the question of nice reductions of varieties (e.g. [this][1] or [this][2]). 

It appears that [this question][3] is not a duplicate since the paper of Berthelot et al mentioned there uses rational p-adic Hodge theory.
