 Describe alternate designs that were considered and related work.
 
 1. Just switch to V2-only as the new default!
-
   - No, this would be a breaking change. We have to do this in two steps,
     because we've rushed the way V2 was introduced in 2021, and STILL require
     field copying, even when `signatureV1` is missing. So technically there was
     never "V2", it was more like "V1.5". Only with this IPIP, we finally
     adjust validation to only care about CBOR values when there is no `signatureV1`.
 
 2. Why keeping the outer protobuf envelope? Could we make IPNS DAG-CBOR-only?
-
    - Due to how long it takes for decentralized network nodes to upgrade, we prefer evolution rather than revolution.
-   - Protobuf is an useful envelope for two reasons:
-     1. ensures the opaque V2-only record can be passed and stored in existing infrastructure
-     2. allows us to evolve IPNS record ("V3") in the future without impacting existing infrastructure
