Too broad warning about missing toml package

[gcolombeau]

The warning about the missing toml package is not restrictive enough in my opinion. At the moment, it is issued every time a pyproject.toml file is detected even if there is no specific configuration in it for isort. I don't use the isort package but I use pylint and this behavior adds a lot of noise to the output.

Would it be possible to improve this by first checking if the toml file contains an uncommented line [tool.isort] to not issue the warning if one does not want to specify some configuration in this file?

This should be fixed in the latest release: https://github.com/timothycrosley/isort/releases/tag/4.3.16

Thanks!
