These are things lacking a PEP which, if solved, would solve a demonstrated pain point in the ecosystem. # Index priority - A lot of work for pip to implement # Consistent metadata across all wheels in a release - What data is used to select a wheel? - Tags - Interpreter - ABI - Platform - `requires-python` - Probably could use `in` since lock files introduced the concept - Consider the set of what's compatible is complete much like how 'packaging' generates the full list - E.g. `"manylinux_2_28" in platform_tags` # SBOMs in `pyproject.toml` - Probably should be a list of globs # License for source code for the project - I.e. not about what's contained in the wheel
