a leap to allow a single entity to inject blackholes for any prefix.

Spamhaus has been distributing their DROP list by BGP for years.  The
world hasn't ended, and I can't recall the last time it had a

The Spamhaus context is different: I know people take that DROP BGP feed
and converting it into ACLs applicable locally on their mailservers, I
don't know of people injecting these prefixes straight into the core.
