Review Comment:
Fine, but just want to say I think String.format is over-used, such as here.
Good 'ol String concatenation is simple.

Review Comment:
It [was a deliberate decision](https://stackoverflow.com/a/23177907/92186)
of Java architects to make it hard to go from an Iterator to a Stream. In
light of this, maybe we should avoid returning Iterators from our APIs, I
suppose. Just thinking out loud; your change here is fine.

Review Comment:
This is a Java gotcha! [Java 19 has an
substitute](https://bugs.openjdk.org/browse/JDK-8186958) but obviously we're
not there yet. Maybe we continue to use Guava for this or have our own
utility? Or just use 2x the size?

Review Comment:
Why wrap with unmodifiable?
Come to think of it, can't you do subset.sort().forEach(...) ? No copying
is needed either; I looked.
