PEP 723: Embedding pyproject.toml in single-file scripts

Another possibility is to define a new [run] table ala Projects that aren’t meant to generate a wheel and pyproject.toml and that’s the only thing allowed in a script (i.e., really lean into the idea of this is replacing requirements.txt for the simple case and then scale up). And to be clear, I’m not trying to guide you or anyone else towards this, but this is an option that is sitting in the back of my head if [project] becomes the stumbling block while embedding TOML is not.

This is very close to a TOML-based variant of PEP 722, with run.dependencies as the dependency block data, and all other sub-keys of run as “for future expansion”. I’d support exploring this as a combined version of 722/723, if we could address our other differences of opinion over format.

But I’m not sure how this links in at all to pyproject.toml, except in the sense that “Projects that aren’t meant to generate a wheel and pyproject.toml might end up with something similar, but we don’t know that for sure yet”, so if we do go down that route someone would have to explain that to me.
