Kollár's non-uniruledness conjecture for general very ample divisors

Let XX be a smooth projective variety and H|H| a very ample linear system on XX such that KX+HK_X+H is effective.

Kollár's conjecture. A general member HHH\in |H| is not uniruled.

The preceding proposition establishes a sharp degree bound for hypersurface sections in the case of linear subspaces, while this conjecture proposes non-uniruledness under the broader adjoint-effectivity condition. The source presents it as a strongest variant that could be true and does not state a resolution.
