Sure it does, unless you're using it in a bizarre way.
That Tavern Lock in Hommlett is still a Moderate DC for a 1st-level character. Your epic-tier rogue can pick it with a chicken leg or a firm knock at that point.
The Next DC chart is just the 4e DC chart with the "level-appropriate" treadmill removed. Bounded accuracy and all that. It's mostly good for the same stuff, only now your fighter with 8 dex can pick locks pretty well because your DC range needs to stay exceptionally narrow to account for constrained bonus ranges.
