No Hostile Mob Spawning in Villages

I'm looking forward to the addition of the Pillagers, but trying to keep villagers safe from Zombies is difficult enough as it stands. You have to spend a lot of effort lighting villages, often at the cost of aesthetics to prevent things spawning within the bounds of a village, or even indoors. It's cool that there is an element of guardianship, but I'd rather not have to plop torches down all over the place. I would like it if you could make it so that hostile mobs don't spawn within the sphere of a defined village, and instead come from outside it.
