If the lower court understood the present moment, this would be its response:
"The court is surprised this needs to be said, but anything related to a coup attempt is not an official act. That includes all of the conduct in the indictment. Trial begins September 1st."
Opinion basically comes down to "official actions are immune, unofficial aren't" and the court says that since lower courts have not made a determination on that question, they need to go do that. Beyond me to determine how feasible that is, but absolutely delays the trial.
Except that decision would be immediately appealable and the trial would once again be stayed for several rounds of appellate review. (Barrett addresses this point explicitly.) A court motivated to prevent a trial before the election couldn't have done more -- though we mustn't inquire into motives
Which, we know will simply get challenged by Trump's lawyers again, trying to push the questions of what are official acts BACK to the SC as needed for time.
