+# FLAKE FEEDBACK:
+# - if flake inputs are meant to be human-readable, a human should be able to easily track them down given the URL.
+#   - this is not the case with registry URLs, like `nixpkgs/nixos-22.11`.
+#   - this is marginally the case with schemes like `github:nixos/nixpkgs`.
+#   - given the *existing* `git+https://` scheme, i propose expressing github URLs similarly:
+#     - `github+https://github.com/nixos/nixpkgs/tree/nixos-22.11`
+# - need some way to apply local patches to inputs.
