Need for historical prefix blacklist (`rogue' prefixes) information

Hi Matthew,

Quantum computing exists as POCs, IBM being one of those advertising them
and announced to extend their project. There are others on the market,
Amazon advertised quantum computing as a service back in 2019:
https://www.theverge.com/2019/12/2/20992602/amazon-is-now-offering-quantum-computing-as-a-service.
The bottle neck of the current technology is scalability: we will not see
QC as personal computing level just yet (to go in more detail, current
technologies work at cryogenic temperatures, thus they are hyper expensive
and not really scalable), but they exist and one could be imagine they
are/will be used for various tasks.

On the other hand, you've actually commented every word of my mail, minus
the stated question. Thanks.

Best Regards,
Dora Crisan
