Villagers and DoMobGriefing

I have recently come across a problem, I like to play a casual survival where I have mob griefing off but villagers will not reproduce if that is turned off.

Farmers won't farm and no villager will pick up food that I drop for them

I propse a way to only turn off hostile mob griefing, that was villagers can still breed and hostile mobs cant grief.

Thanks for your time,
