In pressure cookers and probably other cooking utensils, there are inserts that prevent the food from lying directly on the base of the pan. This ensures that there is no or much less burnt food or the inserts are used to ensure that the food is not directly or only barely in the water and can therefore be steamed by the rising water vapour. The inserts are easy to insert - but they can only be removed if, for example, there are large enough holes in the support surface through which you can grip the insert with your fingers and then pull it out. How good that someone has thought about this and found a practical solution. What initially looks strange - this insert with large holes - ultimately proves to be extremely valuable in use. Nowadays, when everyone thinks they know everything better, trusting experts is not an option. But every now and then it really does pay off.
I wish you an extraordinary day!
