Is the A1 a little unstable on the tabletop? (and fix)

I’ve only had my A1 for a few weeks now and I’m really very happy with it compared to other devices.
There is only one thing that bothers me a little - if I mount a full 1 kg roll on the top-mounted roll holder (I don’t have an AMS), the A1 tends to tilt backwards a little when the printing table moves forwards and backwards quickly.

I also notice this when I push up a little with my hand at the front - it tilts slightly backwards. I can also see this in the print image due to some warping, especially when the print grows a little higher.

So I built myself a stabiliser, which solved the problem for me.

Is it just me, or is the slight tilting backwards normal?
Otherwise, I invite everyone with the same problem to try out the stabiliser.

My friend, I can recommend this friend to you. If there is an imbalance in the device, this will solve it. A1 Z-Axis Stiffener - Solid Feet - Remix/Feet Plug

For reasons of space alone, I cannot and do not want to print such extensions. And in fact, the small stabilisers are perfectly adequate. It’s certainly interesting for people who mount their AMS on the printer, but for me the space requirement is the most important point and my AMS stands on its side.
