Edit 2: This isn’t exactly confirming a a partial or full rework of the 787, rather saying that when the 787 arrives, it’s gonna be easier to make the instruments. Obv open to interpretation but this is the most obvious way to take it.
I think the point of this conversation on Reddit is to show that when the 787 gets a rework, the instruments from the Max will be reconfigured for the 787
I mean all people care about is to have a 787 rework come as soon as possible. Though having to use the 737 MAX instruments as a base will speed up if/when it gets reworked
