Marking CONFIG_SCSI_VIRTIO=y enables initrd-less boot on generic kernel, enabling any Ubuntu installation to be lifted from any hardware and converted into a VM which will, even with corrupted initrd and missing modules, be able to boot by default. This is an extremly useful property to have on all ubuntu kernels. Separately, this also removes the need for linux-kvm kernel flavour, as all the changes it has are now incorporated into generic flavour & cloud-images.

This generally has not been a problem as initramfs has been used. However, as there is recently an interest in booting without initramfs it would seem to make sense to have popular drivers builtin to -generic to allow that. Also, from a priority perspective, if we're going to have any block devices builtin to the -generic kernel, then i'd think that virtio and virtio-scsi would make more sense than an IDE driver. I understand there are tradeoffs involved.
