It was deprecated in 6.0 although as you say why it's not deprecated on OSX and why the docs haven't been updated to reflect it I don't know, from the header ..
__OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_6,__MAC_NA,__IPHONE_4_0,__IPHONE_6_0)
The other methods aren't deprecated.
There's a long and heated discussion about it here https://devforums.apple.com/message/733386#733386, I think there were a few valid use-cases for it but I do understand the explanation given by DAS (marked as answered in that thread) about why it didn't do what you might expect in some cases. If you want to check a queue is one you think it is then the set_specific is the right API.
