Also interested in this as a general point.
If you're doing user driven Autopilot and have "Block device use until required apps are installed if they are assigned to the user/device" in your ESP profile set to the apps you want to be installed instead of all, the other PMPC updates shouldn't process during Autopilot and this should be a non issue as far as I'm aware.
I don't think the above really applies if you're using pre-provisioning though.
