Weird data design on "resteems"

A custom JSON operation: Follow

When you follow someone, you broadcast this data into the blockchain:

["custom_json", {
    "required_auths": [],
    "required_posting_auths": [<follower>],
    "id": "follow",
    "json": ["follow", {
        "follower": "",
        "following": "",
        "what": ["blog"]
    }]
}]

Can't say the best design, but looks like okay. Stop here for a moment, and think how would you design the resteem operation with a similar convention.

resteem operation

When you resteem a post, you broadcast that into the blockchain:

["custom_json", {
  "required_auths": [],
  "required_posting_auths": [""],
  "id": "follow",
  "json": ["reblog", {
      "account": "",
      "author": "",
      "permlink": ""
  }]
}]
