1. Add a warning when the feature is being used.
2. Disable the feature by default, putting it behind a deprecated feature flag.
- If disabling the feature started out as an opt-in experimental feature, turn that experimental flag into a no-op or remove it entirely.
For example, `--extra-experimental-features=no-url-literals` becomes `--extra-deprecated-features=url-literals`.
For example, `--extra-experimental-features no-url-literals` becomes `--extra-deprecated-features url-literals`.
3. Decide on a time frame for how long that feature will still be supported for backwards compatibility, and clearly communicate that in the error messages.
- Sometimes, automatic migration to alternatives is possible, and such should be provided if possible
- At least one NixOS release cycle should be the minimum
