They never automatically loaded.
And also, automatically loading may cause problems, like if you wanted to try out a new build, but everyones' keycount variable is already like 20, so they can get right though the new build. If you deleted the saved variables, everything else would be lost, and what if you wanted to switch back?
What if you hosted a freebuild and someone changed their keycount? It would automatically load once the server goes back to GENERIC BLRPG SERVER.
