I just noticed, no record of scrub in Console.
True, we can seek related information with commands such as
zpool history poolname | grep scrub
… but I wonder whether it will be useful to have, in addition, some record of events in the Console view of all messages.
Thinking not only of the ZFS enthusiast audience; thinking also of analyses in Apple Developer and other areas that may be less familiar with the ZFS/ZEVO experiences.
(Example: an end user might run sysdiagnose to gather performance-related information, but a different person receiving that information might not realise that the gathering coincided with a scrub.)
