I couldn't agree more and feel that it's so important to the health and safety of our little ones.
Speaking of weight, we also have to take some responsibility once a toy comes into our home. I have a feeding dish/toy that I use daily in any given cage. The dish itself is safe and has proven itself through many washings, uses, etc. However, the other night, I chose to use a regular c-link (the small ones that often come with pouches and toys) to hang it from the top of the cage and before long, there was a crash. Though the toy itself can withstand the weight of 4 large gliders (all well over 100 grams), the c-link did not and snapped, sending the toy and gliders crashing to the floor of the cage.
Definitely something to think about when you hang your toys/dishes, etc.
