Mavericks (and server 3.0) was released on October 22nd.
December 19th the update was released for their vpn issue. Less than two months does not equal "like half a year".
The issue was vpn behind nat wasn't working as expected, copying raccoon over from 10.8 server fixed the issue (not ideal but it took all of 5 mins).
