This is an excellent change, because Ember does not allow (afaik) dynamic swap out of tags, e.g. <table> or <tr> to <div> using bindings, unlike classes, which it thankfully does!
That means if a <table> is in the root of a component template, you are kind of stuck with it unless you override the entire thing, which would otherwise be a bit of an unnecessary overkill.
In short, I APPROVE!
