Generalized Lelong-number vanishing conjecture in nef codimension

Let XX be a compact Kähler manifold of dimension nn, and let kNk\in\mathbb{N} satisfy 1kn11\leq k\leq n-1. Let αH1,1(X,R)\alpha\in H^{1,1}(X,\mathbb{R}) be a big class. Say that α\alpha is nef in codimension kk if ν(α,Z)=0\nu(\alpha,Z)=0 for every irreducible analytic subset ZXZ\subset X of codimension at most kk. Generalized Lelong-number vanishing conjecture. If α\alpha is nef in codimension kk, then

ν(αnk,x)=0\nu(\langle \alpha^{n-k}\rangle,x)=0

for every xXx\in X. This generalizes the preceding conjecture by imposing nefness in codimension kk and considering the corresponding non-pluripolar power. The source proposes it as an open extension; the case k=1k=1 recovers the preceding conjecture.
