I find it odd that overrides depend on the config file format. I'd expect the options to behave the same way regardless of the config file format.
At least it should be noted that default of base option is format-dependent above.

Achieving this goal would require that the syntax for the new file format to be very ugly. testenv:whatever Is very much something we inherited in the INI world. Furthermore, this is already the case when using setup.CFG over tox.ini.

If you read the configuration file format introduction section, it clearly calls out the differences.

I'd mark TOML config as experimental until all these are supported. Supporting those may affect the TOML file structure.

I disagree. Some of these features I explicitly do not want to support in the new format (such as conditional factors). The TOML file Format is just not a good match for it.
