Hi Ernie, "Many" in this case refers to "N", which is "0 ... N", so I'd say while it is techincally correct as-is, perhaps more precise would be to say "1-to-0..1" gatherer, since for every element in, there is 0 or 1 element out.
Many-to-one would be 0..N -> 1, which means that an empty input would yield a single output.

In https://openjdk.org/jeps/473 it says As another example, Stream::filter takes a predicate that determines whether an input element should be passed downstream; this is simply a stateless one-to-many gatherer. Shouldn't this be "many-to-one"? -ernie
