Neglecting it as a cosmological parameter would be premature however, as more stringent constraints on $\\Omega_{\\rm K}$ at around the $10^{-4}$ level would offer valuable tests of eternal inflation models and probe novel large-scale structure phenomena. This precision also represents the \"curvature floor\", beyond which constraints cannot be meaningfully improved due to the cosmic variance of horizon-scale perturbations.
