The BitTorrent protocol reserved 64 bits for protocol extensions with
exactly the same restriction.  The result was massive abuse, chaos and
lack of consistency.  The good thing about ggep keys is that they are
in the alphanumeric namespace and there is no "next" key a vendor can
decide to loot.  It is easy to avoid collisions even without central
naming authority by prefixing or a naming scheme.
