And the overall message is that only the (prefix holder|originating
ASn[s]) can tell you if it is intended or not. Sadly, this is not a
useful metric for a third-party to use to determine prefix annoucnement
legitimacy. Perhaps an update to RPSL to allow for intentional multiple
origins is overdue?
