[PATCH] virtio-spec: add field for scsi command size
...l driver implementations used simple layouts,
and devices came to rely on it, despite this specification
wording. It is thus recommended that drivers be conservative in
their assumptions, unless specific device features indicate that
general layout is permitted, such VIRTIO_NET_F_ANY_LAYOUT or
VIRTIO_BLK_F_ANY_LAYOUT. In addition, some implementations may
have large-but-reasonable restrictions on total descriptor size
(such as based on IOV_MAX in the host OS). This has not been a
problem in practice: little sympathy will be given to drivers
which create unreasonably-sized descriptors such as by dividing a...

So why not a transport feature? Is it just because the SCSI commands
for virtio-blk also require a config space field? Sorry if I missed
this upthread.
