Yes, I see LRU/MRU/whatever as a kludge to allow convenience without being unsafe egregiously inefficient. The fact that it is a kludge is not a criticism because there is clearly no easy answer, and thus a kludge is genuinely necessary. However, I think there needs to be a separate array builder type for "heavy duty" appending operations. In TDPL I would just say that concatenating slices can be inefficient and that people should use array builder for heavy duty appending, length changing, etc., w/o getting into the details.
