Even when we look at anomalous users we don't see symmetrical usage, ie top 10% of uploaders. We also see less contended seconds on their upstream than we do on the downstream. These observations are based on ~500k residential and business subscribers across North America using FTTH (mostly GPON), DOCSIS cable modems, and various flavors of DSL.
It is my thought that when people ask for symmetrical circuits, they are really saying that they would like to see a higher upload. What they have is too slow for their needs. This is especially true for older technology that isn't in danger of being replaced anytime soon. Ideally, I suspect that most people would prefer a more variable approach, allowing for the complete frequency spectrum for upload and download and any combination in between.
Let's be honest, it would be nice to utilize wasted download frequency to send something quicker. Once it gets past last mile, it is usually symmetric anyways. It's funny to watch someone spend an entire day uploading a video to youtube, though. Reminds me of the dialup days; just more data.
