Qantas use their Wing Lights all the time for taxi takeoff and landings on all fleets.
I can’t see any problem with doing it.
I sometimes switch them on in busy disorganized airspace such as Delhi or Jakarta and when crossing busy runways in places like Seoul and Beijing at night, can’t hurt to light up the Jet a little more.
I still remember a Us Air 737 landing on top of a Metro at LAX a number of years ago simply because the 737 crew didn’t see them.

An an old saying referring to Driving in Victoria years ago is relevant to Aviation:—
“Be seen, be safe”
If you wish to talk about stupid use of lights then complain about the idiots that love aiming their nose at you lining up with all their lights blazing in your face......now that is bad airmanship.
