If the intent is to make all interactive editors in base unicode aware then I wonder if you can use similar excuse when window(1) was kicked out but for missing features, i.e. use ports. As for other editors, ed(1) seems to support editing UTF-8. I've used it to read/edit cyrillic and CJK texts in single user mode before found out about ex-vi. And ee(1)... why not add unicode support there as a GSoC?
