Could you build this?
Partial A basic proxy or CLI checking package release dates against public registries is straightforward, but building a robust package quarantine proxy that seamlessly integrates into dependency resolvers across ecosystems without breaking builds requires serious package manager integration.
What it would actually take: The solution operates as a caching forward registry proxy (for npm, PyPI, etc.) implemented in Go or Rust. It intercepts package metadata requests and dynamically filters registry index responses, concealing package versions released within the configurable quarantine window. The difficult parts include handling semantic version resolution logic without breaking client-side lockfile determinism, managing checksum caching, and handling private registry upstreams reliably under enterprise traffic.
