Very important. Once the signal gets into the ground plane from the circuit, there will be a ripple. Ripple may spread and influence the signal in other circuits.
If we don’t have a ground plane, the ripple will last longer and may influence other circuits nearby.

I’ve ordered fabrication and assembly of small PCB batches (100st) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Vervolgens, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.
I see some videos online that shows via-in-pad during manufacturing. But I don’t think it is a good way, is it?
What I would like to know is if ICs also have a limited shelf life and if so, do some types suffer more than others?
