Extension of vanishing and positivity of Chern classes beyond small unbounded loci

From papers

Let XX be a compact Kähler manifold and let chatE=(E,hE)chat{E}=(E,h_E) be a Hermitian vector bundle in the setting of the preceding corollaries. The Chern currents cs(chatE)c_s(chat{E}) and their intersections with an admissible current TT are defined as above.

Extension conjecture. The vanishing assertion cs(chatE)T=0c_s(chat{E})\cap T=0 for s>rankEs>\operatorname{rank}E and the positivity assertion that cs(chatE)c_s(chat{E}) is a closed positive (s,s)(s,s)-current still hold without assuming that chatEchat{E} has small unbounded locus.

This would extend the preceding results from metrics with small unbounded locus to arbitrary metrics in the stated setting. The source does not provide evidence resolving this claim.
