The exception to this was with SHB because they probably didn't want to deal with the complications of tying the job stories to the First, so instead we just got new jobs tied to places we're likely to go to in the future.
And unlike Alisae and Red Mage, it's unlikely that an actual story connection could be drawn between these characters and whoever the job npcs would be, because it seems like the WOL is still going to be the only one who can traverse worlds at will.
I'm not saying chemist won't happen, but to assume that this line is specifically teasing it just feels like a bit of a stretch for me. And if it 'is' teasing a new job, a weird way to go about it because of the divide between the source and the first.
