That was the beauty of Batwoman in the days of Elegy and her first solo. She had a complete, realized world without her direct ties to Bruce and the Batfamily. She had and was beginning to further her own cast, each with the same deliberate care in crafting real and resonant characters; Jake, Bette, Maggie.
So in that sense, it does seem that for this to happen, it was decided to bring her more into the mainstream of other DC comics and continuities. I still think there was enough out there for most fans to realize she and Bruce were more closely related than first written - and that was part of the intrigue - that she went her own way and that she only owed to "The Bat" her inspiration and intention to be as valuable a crime fighter.
