My experience seems to match what Andreas and Toomas are saying: -s isn't
doing what it's supposed to be doing (?).

After using

 	sudo beadm destroy -F -s -v <bename>

to destroy a dozen or so boot environments, I'm down to just this
for boot environments:

$ beadm list

However, zfs list still shows (I think) snapshots for some of the
intermediate boot environments that I destroyed:

$ zfs list -t snapshot

Now I have to figure out how to map the zfs snapshots to the boot
environments that I kept, so that I can "weed out" the zfs snapshots
that I don't need.

I appreciate all the discussion and info my question has spawned!  I
didn't anticipate the issue being as complicated as it appears it is.
