Why doesn't pip write installed packages to pyproject.toml?

• This tool would also presumably have to vendor its dependencies to be bundled with the CPython installer, like pip does right now, so I don’t see the dependencies being an issue
• I agree, we could have long discussions and get nowhere. I would say firstly there has to be some appetite on the CPython side to bundle such a tool, and secondly, there has to be at least one tool willing to go through the requirements to be bundled. Unless both points become true it isn’t worth spending energy on discussing

To follow up on these two.

1. Is anyone aware of a tool other than pip which is willing to switch to a “pure Python only, vendor everything” policy?
2. As one CPython developer, I’ll say that I don’t have the appetite to get CPython sucked into the “which tool is best” controversies this would involve. To get a more definitive answer you’d need to ask the SC, though.
