It might be if a beginner does it to a saw initially, but the same beginner should progress to the level of skill to be able to make that fix easily.
(the importance of how different fixing the two is might be negated by LN's return policy - they may fix mistakes, including those made by muppets. I don't have any new production saws, though, so I don't know what any of the places would do. Putting together three from parts and replacing the plate on another old english saw, I certainly appreciated the ability to adjust the back easily until the entire assembly was straight).
