Hi! Flox employee here and pulled from our Head of Product:

Flox will match the most compatible Nixpkgs version given the declaration in the manifest. We are working on a robust service to allow better searching across time to dramatically expand the amount of software available.

We're working on a few solutions to this--allowing flake references in the Flox manifest and offering a robust solution as a product feature.

Flox is compatible with language specific package manager--and provides suggestions and auto detection of existing package managers. You can use the Flox shell hook to initialize the project in the language specific package manager of choice and Flox will suggest this to you if it sees you're using a known package manager (such as requirements.txt for pip, yarn.lock for yarn, etc).

Hope this helps
