I don't think Han unification is as evil as people make it out to be: the characters that got unified do share the same semantic meaning across languages, whereas Latin vs Cyrillic there is no semantic equivalence since letters are purely orthographic glyphs. The thing that sucks is that there's no real inline way (variation selectors, kind of) to select the language for the CJK glyph.

It doesn't in practice. For example: 机 in Japanese means "table", while the same codepoint in Simplified Chinese means "machine" (i.e. 機 in Japanese).

For that example, in Chinese 机 is an alternative orthography of 几 (https://en.wiktionary.org/wiki/%E6%9C%BA#Etymology_2) as in e.g. 茶几 – it's not perfect, but language is messy and I don't think Unicode did the worst job of a messy situation.
