A friend of mine was inspired by Yukari's attack tables, and shogi "byteboards" [SIMD techniques on mailboxes] to write two articles about using SIMD to accelerate attack tables, featuring heavy AVX512 usage, and a pcmpestrm-based ray attack approach.
I think this is really exciting, because a mailbox-y approach at bitboard speeds (as implemented in her engine Rose, which achieves 450 MNPS bulk startpos perft(7)) could permit HCE implementations using information too costly for bitboard engines to consider.
