My point;
The plot demands it be completely impervious to everything, several points in the plot suggested they used experimental high yield devices against the shields and absolutely nothing happened.
Because the plot demands it be
completely impervious doesn't mean that FS2 is magically more powerful and would be able to get around it's
complete invulnerability.
The ship was unique so far as we know in canon, and that still makes it special.
The ship had no weaknesses beyond it's game ending one in canon, and that still makes it special.
Again, physics don't matter.
As for the iceni/snipes, don't mistake a plot device for mission design trying to prevent people who are so horribly stupidly ****e at the game that they need those flags to stop them being stuck in the game.
