well technically Trading is already in. As you can push random stuff into your ship then offer it to anybody willing to buy it. Which of course makes cargo transport a given. I dont know why somebody felt the need to list that in the first place once trading is established, the one pretty much necessitates the other but oh well, bloating isnt restricted to the game features I guess.
Piracy is already in as there is no shortage of random people shooting at you if you run across another player. Smuggling can be argued but in combination with roleplaying yeah...smuggling is already in.
Also under roleplaying you can let yourself get paid to do certain stuff so that covers the Mercenary profession. And the same counts for bounty hunting.
So I dont know what you guys are talking about. Everything listed in 2016 for 3.0 is already implemented, whatever we get in 2017 is just a bonus /scoff
