Is ServerVector broken in OpenLayers 3.5?

Question

Is ServerVector broken in OpenLayers 3.5?

Just running the following gives an error:

var wfsTest = new ol.source.ServerVector({
    format: new ol.format.GeoJSON()
});

The error is: "Object doesn't support this action"

Am I doing something wrong?? It used to work fine in previous OpenLayers 3.x versions.

According to the change log of 3.5.0:

The ol.source.ServerVector class has been removed. If you used it, for example as follows:

var source = new ol.source.ServerVector({
    format: new ol.format.GeoJSON(),
    loader: function(extent, resolution, projection) {
        var url = …;
        $.ajax(url).then(function(response) {
            source.addFeatures(source.readFeatures(response));
        });
    },
    strategy: ol.loadingstrategy.bbox,
    projection: 'EPSG:3857'
});

you will need to change your code to:

var source = new ol.source.Vector({
    loader: function(extent, resolution, projection) {
        var url = …;
        $.ajax(url).then(function(response) {
            var format = new ol.format.GeoJSON();
            var features = format.readFeatures(response,
            {featureProjection: projection});
            source.addFeatures(features);
        });
    },
    strategy: ol.loadingstrategy.bbox
});

This is still helping in 2020. Going through an OL 3 tutorial and to help me understand better I'm trying to also do them in OL 6
