I guess they wanted to bring the novel into the backstory of the series and have Quincy be related to the Belmonts, in turn leading to the "Morrises take over from the Belmonts" idea.
Bloodlines had a surprising amount of story bits written for it. Like direct implication of the Lecardes being related to Dracula, an explanation for the Alucard Spear, and a family tree with a shitload of new Belmonts and branching families.
