I think ConTeXt already does (or parts of it). Normalisation is mostly
about data table, there is no much code that would justify depending on
a beast like ICU. IMO normalisation in context of luatex should be done
very close to the OpenType engine to allow making informed guesses about
what form would give the user best output which depends, to some extent,
on font features.
