There's a two-line implementation in terms of methods we already provide:
public static <A, B> Iterable<B> flatTransform(Iterable<A> collection,
Function<A, Iterable<B>> functor) {
Iterable<Iterable<B>> iterables = Iterables.transform(collection, functor);
return Iterables.concat(iterables);
}
I don't see any pressing reason to add flatMap to the library.

Fair enough that it can be done in two lines, but why not have it there for
others to
make use of?

Because that way lies madness.
We only want to provide two-liner convenience methods for the things users do
very,
very, very, very often. See also
