We don't use reverse listing in any of our code, outside of tests, and it is only exposed through libuplink in the lib/uplink.(*Project).ListBuckets() API. We also don't know of any users who might have a need for reverse listing through ListBuckets(). Since one of our prospective pointerdb backends can not support backwards iteration, and because of the above considerations, we are going to remove the reverse listing feature.
