I think lines 66 through 80 in the example config file^ at the root of this project could be updated with this code change so that it continues to provide an accurate example

[stephengaudet]

more important than the accuracy of the example config file, I think the implementation is not entirely correct.
this config file has "attestation_with_dal" as a child of "generic" when it should be a sibling to "generic", and so, Signatory should error on start with the following:
tezos: tz3MhmeqpudUqEX8PYTbNDF3CVcnnjNQoo8N: log_payloads: true allow: generic: - transaction - attestation_with_dal block: endorsement:

however, Signatory starts with the above config. notable, Signatory does error on start with the following:

tezos: tz3MhmeqpudUqEX8PYTbNDF3CVcnnjNQoo8N: log_payloads: true allow: generic: - transaction - completely_incorrect_config_entry block: endorsement:

So, we should be checking that the generic block has only the "kinds" that are valid. operations that are not kinds of generic should also cause error (like attestation_with_dal, attestation, preattestation, block..)
