Hearing about how snapshots work over the years during APFS sessions made me immediately think of 2007/2008 when they were describing the tech that eventually became Time Machine, but it wasn't a one click operation yet. As a perverse experiment, do we know what happens if you take an APFS SSD and try to format it as a TM volume? Guessing it's still not pretty despite the fact that HDD's under APFS are PNG, but directory hardlinks are gone. Does it work, but just fill up the disk - no deduping?
