That's not the only reason, though. There's other factors going into that decision that make it totally rational: APFS isn't designed as a server file system.

That's not the only reason, though. There's other factors going into that decision that make it totally rational: APFS isn't designed as a server file system. It's meant for laptops, desktop and most importantly (to Apple) mobile devices. Note that most of the devices are battery powered. That means "redundant" error checking by the FS is a meaningful waste. That's not to say they might not add error checking capability in the future, but it makes total sense to prioritize other things when this file system is mostly going to be used on battery powered clients basically never on servers.
