For whatever it's worth, the toml library uv uses doesn't support streaming parsing: https://github.com/toml-rs/toml/issues/326

I'm not sure if it even makes sense for a TOML file to be "read incrementally", because of the weird feature of TOML (inherited from INI conventions) that allow tables to be defined in a piecemeal, out-of-order fashion. Here's an example that the TOML spec calls "valid, but discouraged":

    [fruit.apple]
    [animal]
    [fruit.orange]
So the only way to know that you have all the keys in a given table is to literally read the entire file. This is one of those unfortunate things in TOML that I would honestly ignore if I were writing my own TOML parser, even if it meant I wasn't "compliant".

TOML as a format doesn't make sense for streaming

- Tables can be in any order, independent of heirarchy

- keys can be dotted, creating subtables in any order

On top of that, most use cases for the format are not benefitted by streaming.
