I don't know. I've been thinking about this as I've started working on the EntityContext. I don't know if it makes sense to have inputs like `name="title"` for top level entity properties, or `name=Articles[title]` for the top level entity properties. Having the `Articles` prefix, requires including it in associated inputs as well so `name=Articles[user][username]` and `name=Articles[comments][0][comment]` for example.

I'm tempted to not include the prefix so the HTML, and controller code is simpler/smaller. `$a = $this->Articles->newEntity($this->request->data())` vs. `$a = $this->Articles->newEntity($this->request->data('Articles'));` as an example.
