Delving Deeper =/ Original Edition Characters, But Both = Labyrinth Lord

Apparently Brave Halfing's Delving Deeper is going to be directly compatible with the Labyrinth Lord rules (much like their edition of the S&W White Box rules were with Swords & Wizardry).  Which is a very interesting development.

And finally, with the blessing of Dan Proctor, Delving Deeper RPG will be extremely compatible with Labyrinth Lord. Apart from obviously emulating the rules of the same games-of-origin, we are intentionally using Labyrinth Lord mechanics and terminology so that Delving Deeper will be part of the Labyrinth Lord extended family. This means that modules and supplements produced for Delving Deeper will be easily compatible with Labyrinth Lord and vice versa. (From Brave Halfing Publishing's Site)

My question is this: What is up now with LL's Original Edition Characters supplement?  Obviously Delving Deeper is going for a different approach then OEC, but does Delving Deeper really make Labyrinth Lord the Rosetta Clone?  Dan Proctor says so, but if that's the case, what was Labyrinth Lord with OEC and the AEC?  Wasn't that the clone that covered the major editions?

Look, I'm ready to put my cash down for DD, as I know Brave Halfling does top notch stuff, but I thought the break from S&W was to allow then to take their own direction.  This seems like they are hooking their train car to the LL engine... not a bad thing, but not what I expected either.

Still, like I said earlier... a very interesting development.
