Interesing. But it kicks in the raw payload expression in nftables.

# nft list ruleset
table ip filter {
        chain INPUT {
                type filter hook input priority filter; policy accept;
                @nh,96,24 8323072 counter packets 0 bytes 0
        }

Would you send a patch for nftables too? There is already approximate
offset matching in the tree, it should not be too hard to amend.

Thanks.
