2Authored explanation
UNKNOWN as of 2026-07-31. The MathOverflow page remains unanswered. Guillemin, Legendre, and Sena-Dias derive the relevant first-variation formulas in a paper devoted to this exact question, while the dated citation and exact-phrase search found no later proof or counterexample.
A complete resolution must satisfy this condition: Prove that for every compact connected Kahler manifold and every Kahler class, the metrics with simple scalar Laplace spectrum form a residual subset of the fixed-class metric space, or exhibit a specific manifold and class for which that subset is not residual.
