Very much so. And one may add that the implementation of UAX#11 "East Asian Width"[1] was done in a myopic, backwards-oriented way in that it only distinguishes between multiples 0, 1 and 2 of a 'character cell' (conceptually equivalent to the width one needs in monospace typesetting to fit in a Latin letter).
