So in your opinion APFS ins't a failure that barely worked for about half a year after it's public release ?
Caused problems for almost every software where a patch was needed by the devs (namely docker, sure you could find more examples).
I actually had to reformat my drive because Disk Util.app on a APFS formatted drive could not handle bootcamp correctly on release and it foobared my entire drive.
To their credit they get it right when you give them some months and a userbase of millions of people. I simply wish they did all that before they actually publicly release their latest botch and enable it by default on every device.
