If you Blockade a planet or trade route do you gain rescources from doing so?

I read this was the intention within the design docs but did it make it in (I havent played enough to test this for my self yet)

Here is the exert from the design doc:

Blockading

Blockade power

Who can say trade without also saying piracy? Any fleet will have a blockading power computed from number of command points, specific modules and possible faction affinities. This defines a max blockading power for the fleet, in % of leeched income from the trade route.

A faction fleet can blockade any hostile node that takes part in a trade network. The amount of trade leeched from the blockade will increment progressively per turn, until it reaches the max blockading power we computed earlier for the fleet. Players will also be able to hire privateers (mercenaries) from the market that won't show a specific ownership; using these units, they will be able to also blockade their allies or neutral trade networks without needing to declare war.

Hard point

Blockading a trade hard point (branch or HQ) will completely stop any route connected to it. The victim player won't receive any income from it, while the blockading player will receive up to their max blockading power in leeched income. As soon as the blockading fleet moves or is destroyed, trade will resume.

Systems on route

In the same idea, a player can block any node that is part of a route. In this case however, income is not completely stopped, only reduced by the corresponding fraction in blockading power. As above, when the raiding fleet moves or is destroyed, trade (and income) will resume at full capacity.

That it something I want to tests, sound like a fun way to get resources.

I can confirm that hiring pirates through the "buy pirate mark" gives resources at the end of the contract (pirate fleets destroyed or target pays to stop contract or pays for relations for non-agression pact). There's a screen that pop-up at the end of the pirate mark, and I won some gold & resources present on the target system this way.

I would assume that the same exists if you blockade a system with your own fleet (or fleet disguised as privateers) if you can get it with pirates already.
