@Herman30 You could well be right.
But:
Pictures of the Kelly Kettle in action depend very much on the state of daylight when the photo is taken.

Above is an evening shot.
Below is full daylight. The state of the fires are not much different.
Like any tool, you learn how to use it.
I start mine with a spark and tinder in the fire pan base, then a few flakes of wood. Then I put the kettle onto the base and blow up a good fire via the chimney effect. A few long thin sticks down the chimney are designed to burn away before boiling and I drop a few short pieces in just before I lift the kettle clear to be ready for cooking.
That way I don’t get a cascade of burning wood as I take the kettle from its base.
Edited to add. I don’t use any form of stopper or whistle but I’ve kept a short piece of the cork chain for pouring. I never carry water in the kettle.
Four to six minutes of attention isn’t arduous. There is no rush to be doing anything away from the fire and plenty to do around it. No need for a whistle.
Edited again to say that if you must have a one handed pour then you could try using a decent pot gripper. That’s what my first Eco-Trek (African version) used.
But
Practice cold first so you can anticipate weight, grip and balance.
