What is holding up the divorce if there are no assets to divide?
If there is an issue YOU want to resolve, but SHE is the one dragging her feet...then bifurcation will mean she can drag her feet almost forever, offically single (and may have re-marriage in mind).
So this might be the opportunity to press for what you need settled by telling her "sorry, no divorce until the issues are done".
Otherwise, sounds like it will go on even longer IF she gets what she wants, but you don't with bifurcation.
