Considering the fact that Corvo can use the zoom function also between missions when he's at the Hound Pits and does not wear his mask, I would say it is indeed developmental oversight and/or game mechanic.

And Thomas' line about the gas eating through the masks I've always interpreted as "You have to do this on your own, boss, we can't help you there."
