Adopting/recommending a toml parser?

[bernatgabor (Bernát Gábor)]

I mostly agree with the design choices.

@hukkinj1

So yeah there’s actually quite many differences considering how small the APIs are. Not sure I even have everything listed here.

Based on this, paths ahead:

1. Adopt the toml library, as guarantees backwards compatibility.
2. Adopt the tomli library as is and use the tomli namespace.
3. Adopt the tomli library under the toml id and put it under some namespace (similar to how importlib.metadata is under importlib). There isn’t any good place I see at the moment though.

So I’m personally in favour of 2. Either way, this would likely require a PEP, @hukkinj1 I’m open to writing that up if you co-sign it, probably the least controversial path would be to find a core developer that’s willing to co-maintain the library to also sign-off on it. Perhaps @pf_moore might be willing to help out here.
