Rationale​

Metadata comments should follow the schema expected by annotations. Custom attributes, like category above, should be placed under the custom key, which is a map of arbitrary key-value pairs.

While arbitrary attributes are accepted, they will not be treated as metadata annotations but regular comments, and as such won't be available to other tools that process annotations. These tools include built-in functions like rego.metadata.rule and rego.metadata.chain.
