> Also, APFS removes the most common way of a user achieving local data redundancy: copying files. A copied file in APFS actually creates a lightweight clone with no duplicated data.

No, it doesn't. APFS supports copying files, if you want that. It's just that the default in Finder is to make a “clone” (copy-on-write).

Fair enough; and right now cp doesn't use the fast clone functionality, but it assuredly will. I'm not sure 'cat <file >file.dup' is reasonable for most users.

Just teach everyone to use dd instead - dd if=file of=file.dup :-)

If they patched it to use a different syscall, maybe.
