I understand that using UUIDs, by-id, etc., is an option to work
around this, but then we would have to push IDs for disks in every
server to our configuration management. It does not seem that this
change is really intentional.

SCSI disk detection is asynchronous on purpose since a long time. The most recent commit I know of that changed SCSI disk scanning
behavior is commit f049cf1a7b67 ("scsi: sd: Rely on the driver core for
asynchronous probing").

Please use one of the /dev/disk/by-*/* identifiers as Damien requested.

Thanks,

Bart.
