     * Another way to express this signature would be to bound <V> by @NonNull and accept
     * LF<? extends @Nullable V>. That might be better: There's currently no difference between the
     * outputs users get when calling this with <Foo> and calling it with <@Nullable Foo>. The only
     * difference is that calling it with <Foo> won't work when an input Future has a @Nullable
     * type. So why even make that error possible by giving callers the choice?

				// but if we do see a difference with local domain IPs with
				// hostSlice from etcd then we should update with newer
				// domainIPs, we proceed to do that here.
				bucketsToBeUpdated.Add(bucket)
				continue
			}

			// No IPs seem to intersect, this means that bucket exists but has
			// different IP addresses perhaps from a different deployment.

 * ## Why another URL model?
 *
 * Java includes both [java.net.URL][URL] and [java.net.URI][URI]. We offer a new URL
 * model to address problems that the others don't.
 *
 * ### Different URLs should be different
 *
 * Although they have different content, `java.net.URL` considers the following two URLs
 * equal, and the [equals()][Object.equals] method between them returns true:
 *
 *  * https://example.net/
 *
