I think that at the lounge level people read the internet, pick up bits and pieces, and often make up the rest for themselves trying to appear varsity. Then they write things on riders (often some of their first experiences with such things) that they don't really understand or have the need for. As an old boss used to say; "Those of you that think you know what you are doing greatly amuse those of us who do." Like the festival I mentioned earlier with bunches of performers who'd never played on a stage up in the air before and had all kinds of wild ideas of what it would be like.
Most of the festivals I've played around the Bay Area are provided by Raul. So I typically just give the organizers an input list and have another printed out for whoever's working that day. I've called him to verify backline a couple of times. Whatever he brings to the show is going to be at least as good and typically better than what we normally use so it's silly to try and write down all kinds of requirements.
