Any particular case where one would want to use a FS where it's not recomemded to use more than 80% disk/pool capacity and encryption has side effects?
Because ZFS has one of the most robust RAID systems in an opensource filesystem, and is incredibly mature.
And to be fair, almost every file system will have degraded performance and increased fragmentation above 80/90% full, so this should be considered universal advice.
There is also a legitimate question of how wide spread the issues are with the ZFS encryption feature. The fact this hasn't picked up much steam implies its not a common issue.

The 80% "rule" hasn't been a thing for a while, but any filesystem is going to have issues with finding free blocks as it fills up...
Ext used to reserve 3-5% "for root", but the reality is that you're supposed to free up space if you let it get that full.
