PEP 751 was accepted last year. It introduced pylock.toml, a versioned lock file format for python projects. Allowing hatch to export or install from pylock.toml (if feasible) for the python project would allow for interoperability between different project managers.
Edit: PEP 751 allows for multiple pylock.*.toml files which I believe should be in line with hatch allowing to support different environments.
