GeoJSON layer remove/replace data

The L.geoJson API seems to be missing an API that would make it symmetric:

var layer = L.geoJson();

// we have this
layer.addData(foo);

// we don't have this
layer.removeData(foo);

// or this
layer.getData(foo);
layer.replaceData(foo);

// and if we had this
layer.data(foo); // set the data to foo
layer.data(); // get all data

// we could implement the rest as sugar

Yeah, currently such use cases are handled like this:

layer.clearLayers(); // inherited from LayerGroup
layer.addData(newData);

So GeoJSON class currently acts like a one-way converter of data. But I agree that being able to remove specific objects would be useful.

Note that it is possible to remove a single feature from a GeoJSON layer. As @mourner mentions above, L.GeoJSON inherits from L.LayerGroup, which supports removing single layers.

Add an onEachFeature handler for the GeoJSON layer to keep track of the layers associated with a feature (putting them in a map where the feature is the key and the layer is the value, for example), and then use L.LayerGroup’s removeLayer to remove them.

A simplistic example of this: http://jsfiddle.net/MLuc3/3/

@mourner any particular reason this issue is still open? Any plans on reworking the API? I’d vore for closing.
