That information is often intentionally not cascaded up the chain because the higher up you go, the more rigid the thinking gets - at least in my experience. Upstream doesn't want to hear the bad news or hear about how their idea is dumb. They want us to just do the bad idea and if the bad idea doesn't work out, they want to hang the ICs out to dry.

Maybe some smaller shops are not like this, but the bigger your company is, the more you'll find this type of thinking to persist.

In theory, I do like your idea - anonymously cascading feedback upstream. I just see no avenue for this to succeed in practice.
