I think they do kind of answer that under the "Why not use (possibly restricted) Python syntax?".

I understand their reasoning to be that it would require other tools to know how to parse python. Which is much more difficult than parsing toml

Ah okay, I read this but I've understood it in another way. I thought they meant using multiple variables could become a problem. But I guess it makes some sense to not parse the python ast tree but to parse with a regex.
