     * even any source of data.

     * In the CLI we use a GraphQL endpoint with a query
     * that checks the usage and returns stats like:
     * min/max count and min/max percentage
     * So we know when to allow for a breaking change.
     *
     * Because it returns a boolean,
     * we can't attach any data or even customize a message of an api change.
     * This is the first iteration, we're going to improve it soon.
     *
     * true - NON_BREAKING
     * false - BREAKING
