On a technical level most of the asymmetric techniques just carve up the spectrum/bandwidth (in Mhz) to give more of it to downstream. Or timeslots or whatever. I fully agree with the EFF that you need a decent upload, to support the applications of today and next few years. But to go fully symmetric actually means to lower the download in favour of upload, allocating exactly half of the spectrum to each. So absolutely, once you reach a certain threshold I think most users are going to opt to carve up the spectrum in a way that favours download, just based on typical needs.
