Really? Hasn't that always been the case?
What hasn't always been the case? :)
1) "the default VSCSI controller will not be created" -- no, this is new
with scsi-cd: scsi-disk never was on the default_driver_table in vl.c,
as you said in the commit message for af6bf13 (defaults: ide-cd, ide-hd
and scsi-cd devices suppress default CD-ROM, 2011-05-18). In fact, I
believe you could add scsi-hd there too.
2) "without qdevification, you will not be able to add yours" -- that of
course has always been the case. But I never noticed because there was
no way to avoid creating the default CD-ROM, and this in turn forced the
non-qdev-clean creation of the VSCSI controller.
