Efficient update lists using the key attribute about morphdom HOT 4 CLOSED

By code i understood that instead key using id.
Probably it is necessary to make such changes:
var id = node.id; -> var id = node.id || node.getAttribute('key');
because the ID must be unique for the entire document.

even better:

function defaultGetNodeKey(node) {
    return node.id;
}

function morphdom(fromNode, toNode, options) {

    var getNodeKey = options.getNodeKey || defaultGetNodeKey;
    var id = getNodeKey(node);
