Some of us may remember this (including Sue and Jeff). Jakob Heitz, I, and others have proposed/presented (in the IDR WG) the idea of a range of IANA-registered 4-octet ASN values for the Global Admin field to classify BGP Well Known Large Communities (WKLC). See: https://datatracker.ietf.org/doc/draft-heitz-idr-wklc/ [1]
The above draft was motivated in part by the following GROW WG draft's request plus possible other use cases for WKLC: https://datatracker.ietf.org/doc/draft-ietf-grow-route-leak-detection-mitigation/ [2] Our idea was critiqued for requesting 64M 4-octet ASN values to be set aside by IANA for WKLC. That is only 64 million out of the 4 Billion (a fraction 0.015) 4-octet ASNs. This can be reduced easily to 256K out of the 4 Billion (a fraction 0.00006) if that is acceptable. There would be 9 octets available in the WKLC for the data part. The 256K number can be further reduced to 1K if desired (with 8 octets available in the WKLC for the data part). Details can be found in the above cited draft [1]. We can discuss further the possibilities if this approach gets some traction. Thanks.

Individuals even said, there would be no use for well-known large BGP communities.
