Unless further orders are imposed, I wouldn't worry about it. Ever since they reopened the Fremont factory, they have managed to keep the supply and delivery chain flowing through CONUS and Canada.
One thing that might change is your individual delivery method and location. Late in Q3, Tesla seemed to revise its policy about who gets home delivery vs. showroom pickup. People who were too far from a delivery facility got the car trucked to them. They also open new delivery centers and will reassign you without checking with you first (that's what happened to people on the SF Peninsula when the Serramonte facility opened).
Now, if the factory has to shut down again, then all bets are off.
