If anybody is interested, here's a pretty printed version of the 2.9 (not minified):

{
  "id": null,
  "block": {
    "statements": [
      ["text", "Hello "],
      ["append", ["unknown", ["name"]], false],
      ["text", "! "],
      ["block", ["if"], [["get", ["isFriday"]]], null, 0],
      ["text", "\n"]
    ],
    "locals": [],
    "named": [],
    "yields": [],
    "blocks": [{
      "statements": [["text","Happy Friday!!!"]],
      "locals": []
    }]
  },
  "meta":{
    "moduleName": "my-appgtemplatesapplication.hbs"
  }
}

...And here's the pretty-printed minified version

{
  id: null,
  block: '{
    "statements": [
      ["text", "Hello "],
      ["append", ["unknown", ["name"]], false],
      ["text", "! "],
      ["block", ["if"], [["get", ["isFriday"]]], null, 0],
      ["text", "\\n"]
    ],
    "locals": [],
    "named": [],
    "yields": [],
    "blocks": [{
      "statements": [["text","Happy Friday!!!"]],
      "locals":[]
    }]
  }',
  meta: {
    moduleName: "my-app/templates/application.hbs"
  }
};

...and without the value for the top level block value wrapped in quotes

{
  id: null,
  block: {
    "statements": [
      ["text", "Hello "],
      ["append", ["unknown", ["name"]], false],

      ["block", ["if"], [["get", ["isFriday"]]], null, 0],
      ["text", "\\n"]
    ],
    "locals": [],
    "named": [],
    "yields": [],
