They need FAQ clarification for Bossk already.
They don't need one for Bossk until he's legal for tournament play. Even if they have advanced copies of Wave 7 for sale at GenCon that doesn't mean they're legal for tournament play. That's how it worked with wave 5 IIRC.
I'm still confused: what about Bossk needs any clarification? He's really, really straightforward.
My guess is crew Bossk, to be absolutely certain whether he can trigger or not when already stressed.
"After you perform an attack that does not hit, if you are not stressed, you must receive 1 stress token. Then assign 1 focus token to your ship and acquire a target lock on the defender."
He triggers after every missed attack, stress or not, and you receive a stress if you don't already have one. Resolve those conditions and you get a focus and target lock.
Exactly my interpretation of it, but its the only possible Bossk clarity I could think of. Well, outside the Nashta Pup but that's not Bossk exclusive.
