There are many situations where it would be nice to go back and look at scorecard details - number of birdies, bogies, etc, longest putt sunk/longest drive, tees played, etc. But once you finish a round you can't navigate back to the scorecard - just the total score.
Ideally we could go pull up our scorecards - if not permanently then at least for a period of time (30 days?). We rely on the scorecard to run match play competitions in parallel with a stroke play tournament and if people forget to update the spreadsheet as they play or save their scorecard (both front and back nines!) then we can't compute a match winner.
