Part of what's confusing me here is you're still skipping device 0:0, which is a
"should never happen" entry? (Even ramfs is only major 0 with minor incrementing
per-mount I think?)

Can we just change to print the - - - - entries for a device 0 0 and not have to
change the lib plumbing for the extra flag? Or am I missing something?

P.S. lanana.org is still there but if you click on the "linux device list" from
their main page it's 404. Gotta pull it out of archive.org...
