Seperate ES6 build for a small and modern build

[benedikt-krieger-hyghstreet]

Google Lighthouse Report flags some transforms as deprecated and I think there is no need to transpile classes and the spread operator to work on ES5 javascript engines. It would be nice if there was a build without ES5 support.

Now the client constructor does not work anymore. Am I forgetting something?
The exact same code was running fine before the update from 2.71.3 to 2.86.0.

    "sendTrackingEvents": true,
    "trackingSendDelay": 0,
    "eventDispatcher": {
        "waitForBeacon": false
    }
});
