Have you considered using jsonata?

You might be able to escape some of the weight of carrying around everything in JSON by transitioning to jsonata.

In your example, you use

rule = {
    "name": "basic_rule",
    "conditions": {
        "all": [
            {
                # JSONPath support
                "path": "$.person.name",
                "operator": "equal",
                "value": "Lionel"
            },
            {
                "path": "$.person.last_name",
                "operator": "equal",
                "value": "Messi"
            }
        ]
    }
}

if you were to use the jsonata-python project as part of your engine, you could reduce these to

rule = {
  "name": "basic_rule",
  "conditions": {
    "all": [
      "$.person.name == \"Lionel\",
      "$.person.last_name == \"Messi\""
    ]
  }

or even

rule = {
  "name": ...
  "conditions": "$.person.name == \"Lionel\" and $.person.last_name == \"Messi\""
}

Feel free to close this issue, as it's completely unsolicited input.
