However, this meant that some precomposed characters were "redundant": they represented character + diacritic combinations that could equally well be expressed separately. Normalization was the inevitable consequence.
It is not inevitable. Simply disallow the 2 codepoint sequences - the single one has to be used instead.
There is precedent. Some characters can be encoded with more than one UTF-8 sequence, and the longer sequences were declared invalid. Simple.
I.e. have the normalization up front when the text is created rather than everywhere else.
