MarsSeed [1] filed a deletion request for python-anyconfig-cbor- backend [2]: Only python-anyconfig-cbor2-backend is useful to keep. [a] This one was for very old Pythons that needed the obsolete python-cbor (RFC 7049 implementation, EOL since 2016, upstream repo deleted). [b] python-cbor2 [c] (in [extra] repo) is an actively maintained, fully compliant (and backwards-compatible) RFC 7049 and revised RFC 8949 implementation.
