Do you know any block devices these days that aren't disks or flash drives? I'm pretty sure DECtape is officially obsolete. While magtape had block interfaces (at least in the old Bell Labs Unix), they were not truly (or even virtually, like DECtape) random-access. (I did once try mkfs-ing and mounting a magtape. It was interesting to watch...) So it's a distinction without a difference.
