Just found this to work (e.g. for a future --bind-interface=...):

if (setsockopt(fd, SOL_SOCKET, SO_BINDTODEVICE, "eth0.88", 7) == -1)
        error_printf(_("Failed to set socket option BINDTODEVICE\n"));

BUT it needs privileges / capabilities, e.g. root / sudo or
  sudo setcap cap_net_raw+ep <path to wget|wget2>

So, this doesn't work yet - I just write it for the record.

OPened an issue at https://gitlab.com/gnuwget/wget2/issues/430
