Nobody has written a patch, so 32-bit ARM uses the generic bits, which
are suboptimal (in terms of ABI compliance and protection level) and, it
appears, not really usable.
Even the final aarch64 bits are still pending review by the ARM
maintainers.
The aarch64 bits still have not been committed. It might help if you
pinged your Arm contacts again.
