I think you miss the point.
When CP1251, KOI8-R and other crazy imcompatible things came around, they came around because there was a need: ASCII didn't provide a necessary character set. Now when we have Unicode that embodies virtually all character sets existing on Earth, we don't _really_ need either non-Unicode encodings, or even fixed-byte UTF versions. So a move to any hypothetical FutureText-64 will actually give no practical gain, unlike a move from single-byters to, for example, UCS-2 and then from UCS-2 to UTF-8.
But my main point is another: eliminate all single-byter and fixed-byter zoo and leave one universal encoding. When (if ever) it's time to replace it, we'll do it all and at once, not having those crazy iconvs everywhere.
