I was careful in the introduction to note that this is an opinion piece. There probably is no objective truth on this topic!
I agree with you that examples are important, though I do not typically care whether or not the example code is high quality. As long as it demonstrate the use pattern for a peripheral, I’ve got what I need. One thing I did allude to in the code, is that I like to have all the examples downloaded so I can browse their code. Some SDKs require you use their project configurator to instantiate examples one by one .
