Yeah, it’s a teaser trailer. As in, it’s designed to tease you with glimpses of the movie and give you a vague idea of the tone and feel.
If they were worried about the performances the lead actors were giving they’d have surely picked the best moments and lines and shoved them repeatedly in our faces. All we got was a nice little delivery of a line that had a gentle reference to episode IV and a nice bit of body language when Qi’ra (?) said that line at the end to him.
It’s a teaser trailer, you’ll get yourself in a right state if you read too much into it.
