A lot of these suggestions are heavily opinionated. Which is not necessarily bad, but they seem to mess with existing conventions just for the sake of it (why {pool}:{dataset}?).

You might like this little tool I wrote: https://github.com/rollcat/zfs-autosnap

You put "zfs-autosnap snap" in cron hourly (or however often you want a snapshot), and "zfs-autosnap gc" in cron daily, and it takes care of maintaining a rolling history of snapshots, per the retention policy.

It's not hard writing simple ZFS command wrappers, feel free to take my code and make your own tools.
