While you can do pirates with the RAW, I think the advantage of a Pirate spec would be to capture the "spirit" of cinematic pirate characters. Much like you could make an archaeologist with the Scholar spec, the Archaeologist-with-a-capital-A is different -- she's a tough-as-nails fist fighter and tomb raider. It's a spec to capture the Indiana Jones/Lara Croft/The Mummy archetype. In the same way, a Pirate spec ideally would provide several talents for swinging from chandeliers and witty repartee. I'm thinking all the stuff Guybrush Threepwood tries to emulate in the Monkey Island games, but played for action/adventure more than humor.
I completely get this, and if anyone wants to make a Pirate specialty within the Smuggler career, I'm not saying that is wrong at all. I'm just saying that RAW has it pretty much covered already and pointing out the term "pirate" can mean all sorts of possible career paths and skills so it would be hard to limit it to just one specialty. We don't have a "Criminal" career either, for example. There are all different types of criminals that can be described with RAW depending on their speciality (strong arm robber - Marauder, burglar - Thief, hacker - Slicer, etc).
So, what you are descibing is the iconic Errol Flynn pirate in a space setting? You said, "swinging from chandeliers and witty repartee". I would add fighting and sailing skills (scifi versions). So, with RAW, look at Smuggler (Scoundrel). Core skills would include Coordination (swinging from chandeliers?), Deception/Charm (witty repartee), Piloting-space (sailing skills), Cool & Ranged-Light (fighting skills). Talents for the above include Convincing Demeanor & Natural Charmer, Rapid Reaction, Side Step, Quick Strike. These cover the fighting skills and "witty repartee" and possibly chandelier swinging while fighting depending on your narrative description or exactly what that means. The only thing lacking for talents would be those for pilots and possibly "swinging from chandeliers" if the above isn't enough. Luckily, there are more talents along these lines within the same career (Smuggler) under other specialties the character can easily dabble into (Pilot & Thief).
Could a Smuggler (Pirate) specialty be slightly better when modeling this specific type of priate? Sure. You could design some new talents and toss some Core skills to add things such as Melee and Athletics. But for me RAW has this specific type of Pirate already 90% covered.
Don't take this wrong! I still want anyone designing a Smuggler (Pirate) to share!
Eta: The new Smuggler book doesn't include a "Pirate", but the new Charmer specialty may be something a Smuggler wanting to be an Errol Flynn pirate may want to dabble in.
