They showed a TOS-style Constitution Class Starship in the Fleet Musuem and, yes, I liked seeing that. It reinforced what I think: PIC takes place in the Prime Timeline while DSC/SNW take place in a Modified Prime Timeline. Something else from SNW Season 2 drove it even further home, but I won't get into that here.
But remember:
PIC S1 showed the DIS/SNW version of the Constitution-class Enterprise.
So it must be more wibbly-wobbly timey-wimey than that.
