On one hand, I miss an "rm" interface to kill snapshots as easily
as "mkdir" makes them ;)

Overall, why don;t you use zfs-autosnap service and set up the
amount of regular snapshots you want kept for a particular schedule?
Also in its second (current) incarnation, the service can kill more
autosnaps if the pool runs out of a threshold percentage of free space.

To your original question, see the "snapdir" property on datasets.
