Can confirm this privacy option existed since I installed WhatsApp on my brand new LG G2 back in 2014. I turned it on then right away and never turned it off in all the years and phones I've had since.

The price for people not seeing your "last seen" status, is that you don't see other's people's "last seen" status. Which is fine by me.
