Do you even need to flush the tables and grab a read lock while taking the ZFS snapshot? My understanding was that since ZFS snapshots are point-in-time consistent, taking a snapshot without flushing tables or grabbing a read lock would be safe; restoring from that snapshot would be like rebooting after losing power.

I think you are correct. But then you risk data as you would with the unclean shutdown.
I much prefer to have a known clean state which all things considered should be a safer bet.
Just like some are OK running without fsync.
