The issue is not about being logical or not, the real trick is: this piece of information of the DS being sabotaged by its own engineer is a rationalization of something magical/Force related in ANH, and it was totally unecessary. That’s why I compare that to the midichlorians: going for magic to something… logical, mathematical, biological, rational… it goes 100% against the spirit of the OT and particularly of ANH.
When I get some more time I intend to come back and address Shopping’s main post but for now I’ll just address this.
Nothing in Rogue One contradicts Luke’s achievement in SW.
The struggle in Star Wars is trying to land a direct hit down the thermal exhaust port to set off a chain reaction. Something that all the other pilots proclaim is next to impossible.
That weakness in the design whether it was intentional or not has no bearing on the inherit difficulty of exploiting it.
Thank you.
