@ember/optional-features

This addon provides a straightforward way to manage optional features within Ember.js applications. It allows developers to opt-in or opt-out of specific ember-source features that are designed to remain optional long-term, giving fine-grained control over an app's feature set and dependencies. The tool is intended exclusively for use with Ember apps, not addons.

Key Features

• Feature Listing — Lists all available optional features for the installed version of ember-source via a CLI command.
• Feature Toggling — Enables or disables specific optional features directly from the command line.
• Build-Time Integration — Exposes methods for addons to check feature status during the build process, allowing conditional logic based on enabled features.
• Explicit Setting Detection — Provides a method to determine whether a feature's value was explicitly set by the user or is using the default.

Philosophy

The project emphasizes giving developers control over their application's feature set by keeping certain ember-source features optional and configurable, rather than imposing defaults.
