pip_parse allows us to import third party dependencies, but the imports lack enough information for us to generate an SBOM. It would be useful if targets imported from third party python deps were annotated with a PackageInfo from rules_license (notably, the purl is incredibly useful for generating CycloneDX format SBOMs).

While it might be possible to add this information in a custom way, adopting rules_license allows SBOMs to be generated without adding special logic to each ruleset.
