it's not good to have weight on your steering, and I wouldn't have any on my bikes.
That's your Opinion ..alone.. , I found My Brompton Thrives with weight in the front bag for many years ..
My Bike Friday Has a front Pannier rack on the front Wheel fork , Its fine too.
NB: the bag shown is a Mini Ortlieb, its just a Handlebar Bag , not carrying Bowling Balls ..
