I think syntax typing is a good idea. There are a million ways to format dates and standardizing that saves a lot of pain. Having explicit syntax for types means it's easier to handle arbitrary data or data of an unknown schema, and without it you are forced to assume everything is a string or rely on heuristics which leads to divergent implementations. No semantic whitespace please. Can't tell you how many times I've seen something in GitHub Actions or similar get messed up because someone forgot a space. I don't think TOML is a perfect format and agree it's not great at hierarchies.
