Palindromicity conjecture for hyperplane sections of high-degree complete intersections

Let P=PNP=\mathbb{P}^N, and let XPX\subset P be a general complete intersection of multi-degree (d1,d2,,dk)(d_1,d_2,\ldots,d_k) with d1dkd_1\leq\cdots\leq d_k. Assume that d10d_1\gg0. For a hyperplane HPH\in P^{\vee}, write Y:=XHY:=X\cap H. Palindromicity conjecture. The hyperplane section YY is palindromic. This conjecture generalizes the preceding result for hyperplane sections of general cubic 44-folds, and asks whether palindromicity persists for hyperplane sections of general complete intersections when the smallest defining degree is sufficiently large.
