I can see the practicality argument here. I don't think (correct me if I'm wrong!) that anyone particularly anticipated when we were drafting PEP 518 that the tools section would be used by anything other than build tools - I know I hadn't anticipated that usage. In hindsight it's an obvious thing to do, but it does mean that pyproject.toml is more of a "general project configuration" file than purely a build configuration one.
I agree - I didn't really think about this, but it is obvious in hindsight: we provide one obvious place to put configuration, and people put it there. :-) Maybe pip should be switching behaviour based on the presence of the [build-system] table in the toml file, rather than just the presence of pyproject.toml? (I'm only half following this discussion, so apologies if someone already suggested this). Thomas
