Interesting idea. I've just tried it with a couple of languages:

- TS with Vue: SFC are not really working (it's showing a style change as if the whole stylesheet were replaced with a mostly-identical stylesheet).

- Rust: It doesn't seem semantic at all. It's showing a lot of character-level insertions and deletions that seem worse than how git-diff or GitHub would break down the changes.

It doesn't seem ready yet for what I'd like to use it for.
