Absolutely, but the USB code doesn't care. While topology is important for userspace naming, the kernel doesn't care. I also never advocated removing topology information. We already have it via an ioctl call. I just don't want topology exposed in the directory structure for usbdevfs. In that case, we're forcing the information on everyone if they care or not, and most programs don't care.
