The only reason this seems to be a problem is that apparently operators (or the manufacturer) didn't know about it, since I don't think there's an actual usecase for the aircraft to be powered on continuously for that long.

FTA: It is usual for commercial airliners to spend weeks or more continuously powered on as crews change at airports, or ground power is plugged in overnight while cleaners and maintainers do their thing.
I don’t know how long rebooting a 787 takes, but turn Around Time of an airliner may be too short to do a reboot. http://aviationavi.com/turn-around-time-tat/:
Ryanair a private ULCC of Europe and one of the largest ULCC of the world having a TAT of 25 minutes does not have a seatback pocket.
Wondering why?
Back in 2004, removal of seat back pockets greatly reduced the time for which the Ryanair aircraft stayed on the ground. That’s is because it takes more time to clean an airplane with seatback pockets.
So, that’s 25 minutes from touching down to being airborne again. Chances are the plane is standing still for less than 15 minutes. Long-haul flights take longer (up to two hours, according to https://simpleflying.com/aircraft-turnaround-process/)
Also: it wouldn’t surprise me if you could not refuel an airliner while it is rebooting, all lights may be off for a while, etc.
Assuming the plane spends 50% of its time flying, it kinda lines up with an A check interval.
