That's true, but doesn't affect the point being made: that one can have
both “sequence of Unicode code points” in Python's ‘unicode’ (now ‘str’)
type, and also deal with “sequence of text the reader will see”.

Specialised code may not be needed. It will at least be true that “any
two code-point sequences which normalise to the same value will be
visually the same for the reader”, which is an important assertion for
addressing the complaints from Mortoray's article.
