FWIW, the documentation for GIST has inet_ops in the equivalent table, so it was extra-confusing because I thought SP-GIST's inconsistency must have a reason - though I see now using '\dAf gist' suggests it's similar.
https://www.postgresql.org/docs/14/gist-builtin-opclasses.html

The index in question was replacing a default btree - we'd started using the table to block by range; when reviewing indexes, I found it wasn't used anymore. (I didn't know btree *had* cidr_ops, but that may be for the best, as it didn't help with 'CIDR contains IP'.)
