I don't know why this wasn't implemented back in, because Brian Hicks said specifically said they would return in .60 during the Pax East livestream showcasing 0.60 I hope this will at least remind the devs that this was supposed to be added. This is a huge and important feature that should be in before the stable release, without it doesn't complete one of the most loved survival aspects to DayZ!
Thank you for your understanding,
