I wonder what stopped them using the Enterprise? Was it licensing issues or the fact they didn’t want to repeat the season one finale of Discovery again. Maybe they also thought that it might overshadow everything else.
Because no matter what happened you'd have people upset
"OMG The Enterprise EFG doesn't have a window, how does that make sense?"
"OMG The Enterprise EFG HAS A WINDOW WHAT THE HELL"
"OMG WHY IS TROI DRIVING?"
