Looking into this I found that commit d27769ec ("block: add GENHD_FL_NO_PART_SCAN") introduces this change in behavior. It's not clear to me from the commit's changelog if this change was intentional or not. This comment still remains: /* Don't show non-partitionable removeable devices or empty devices */ so I've decided to send a patch to restore the behavior of not printing unpartitionable removable devices.
