The way I understand it (and the way pywikipediabot uses it) this should give the disambiguation pages starting at Da.
It never listed disambig pages whose *title* starts at Da, it always listed disambig pages whose *sortkey* starts at Da. With the category collation rewrite, sortkeys are now in all uppercase (which is why you need DA to accomplish what you want), and they may have crazier binary formats in the future.
