Almost all existed struct_ops users(hid, sched_ext, ...) need the two APIs. In-tree hid-bpf code(drivers/hid/bpf/hid_bpf_struct_ops.c) can't be built as module because the two APIs aren't exported. Export btf_find_by_name_kind and bpf_base_func_proto, so that any kernel module can use them given bpf community is supporting to register struct_ops in module, see the patchset "Registrating struct_ops types from modules"[1], which is merged to v6.9.
