Yeah, Boeing gets (and rightfully deserves) a lot of flak these days but updating the 20-year-old 777 is very different from updating the 50-year-old 737.
More specifically, the 737 design had so little ground clearance that the bigger, more efficient engines used in the Max had to be mounted in a different position than before. This change resulted in different maneuvering characteristics that Boeing tried to patch with crappy software. The 777, on the other hand, is a much bigger plane with plenty of clearance and the new engines are only marginally larger than the old ones. I don't see Boeing messing with the engine positioning needlessly here, especially in the wake of the 737 Max fiasco.
