How is it right to get the chanc components in October CMS?

[jeanid]

I'm studying the ready draft for October CMS and saw an interesting thing about getting a reference to the product.

{% partial "product" product=this.controller.vars.data.product %}

In summary: there is flame X with a component Essencewhich produces data for presentation on the product page. In particular, a piece of the code is presented below. $data of this.controller.vars.data.product (variably cleared for visibility and irrelevant):

public function find()
    $data['product'] = $this->getPreparedProduct($data['id']);                       
    $result = array(
    "type" => "product",
    "data" => $data
    );
return $result;

The question is: how accurately to obtain data through this.controller.vars.data.product - is that a normal approach or a crutch? Why did I think it shouldn't be that way? $resultwhich is clearly returning somewhere and which can/do be read in a traditional way, why the requested data are derived from a list of variables, I don't understand.

If you can give me a link to the docks where it's written, I didn't see it on official docks.

this.controller.vars.data.product is not necessary to obtain the necessary data, but it is sufficient data.product.
