Sadly it seems it's not quite as straight forward as that. The release is great news and greatly appreciated, it offers lots of additional flexibility and no doubt a lot of hard work has gone into it, but there are some unfortunate bugs currently. From our experience in updating to 1.1, the 'biggest problem' certainly wasn't the server owners (us) being lazy and not attempting to update, as your post implies. That said, we are happy to wait for the fixes to come through. Bugs are an inevitability in development or modification of new programs, I think everyone understands and accepts that, and are supportive of the development team for their efforts.
Oz might mean to wait for MTA SA's new updates and bug fixes to make sure DKR in 1.1 runs smooth and bugless.
You might remember the time at MTA SA 1.0, when there's still lots of bugs. As time goes by and new 1.0 releases(1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5), there were less bugs. I know that 1.0.5 was the most stable version yet.
But on MTA SA 1.1, it has to go all over again, like MTA SA 1.0 days, where bugs are still many. New builds may give less bugs and better chance that DKR might get to 1.1 sooner or later.
