 Since the actual universe is now apparently almost isotropic such a singularity could not occur in our universe.A sufficient condition for a stable singularity to be of physical interest is the requirement that the singularity be generic (or general).Roughly speaking, a stable singularity is generic if it occurs near every set of initial conditions and the non-gravitational fields are restricted in some specified way to "physically realistic" fields so that the Einstein equations, various equations of state, etc., are assumed to hold on the evolved spacetimes.
