First off, thanks a lot for your efforts! TBH, there’s such a proliferation of toml-libraries that despite searching for them, I missed tomlkit, even though it apparently does exactly what I’d need (I’ll try it as soon as I can). This proliferation itself is IMO an argument for inclusion in the stdlib, but reasonable people can disagree about that.
Could you explain your thinking on that a bit more? I’d understand if the API still needs to move quickly, but TOML itself looks like it will be a very stable format, so assuming the right abstraction has been found (granted, that might take 2-3 years) - why should general python users not also be enabled to write the format that is becoming more and more ubiquituous, even in the python ecosystem itself?
