--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This changed with:

            PR c++/80178 - parameter passing for uncopyable classes

            * tree.c (type_has_nontrivial_copy_init): True for classes with
only
            deleted copy/move ctors.
            (remember_deleted_copy, maybe_warn_parm_abi): New.
            * decl.c (require_complete_types_for_parms, check_function_type):
            Call maybe_warn_parm_abi.
            * call.c (convert_for_arg_passing, build_cxx_call): Likewise.

(Which didn't document -fabi-version=12 in invoke.texi)
