+# Deprecate target action support
+
+## Summary
+
+Deprecate `send` and the corresponding target action support.
+
+## Motivation
+
+These are super-old patterns that nobody needs to use in new code. We've already deprecated the `{{action}}` modifier/helper, which was the primary way to interact with this system.
+
+## Detailed design
+
+Things this would target
+
+- `TargetActionSupport` mixin
+  - `triggerAction`
+- `ActionHandler` mixin
+  - `send` method
+- `ActionSupport` mixin
+  - `send` method
+
+> This is the bulk of the RFC.
+
+> Explain the design in enough detail for somebody
+familiar with the framework to understand, and for somebody familiar with the
+implementation to implement. This should get into specifics and corner-cases,
+and include examples of how the feature is used. Any new terminology should be
+defined here. 
+
+> Please keep in mind any implications within the Ember ecosystem, such as:
+> - Lint rules (ember-template-lint, eslint-plugin-ember) that should be added, modified or removed
+> - Features that are replaced or made obsolete by this feature and should eventually be deprecated
+> - Ember Inspector and debuggability
+> - Server-side Rendering
+> - Ember Engines
+> - The Addon Ecosystem
+> - IDE Support
+> - Blueprints that should be added or modified
+
+## How we teach this
+
+> What names and terminology work best for these concepts and why? How is this
+idea best presented? As a continuation of existing Ember patterns, or as a
+wholly new one?
+
+> Would the acceptance of this proposal mean the Ember guides must be
+re-organized or altered? Does it change how Ember is taught to new users
+at any level?
+
+> How should this feature be introduced and taught to existing Ember
+users?
+
+> Keep in mind the variety of learning materials: API docs, guides, blog posts, tutorials, etc.
+
+## Drawbacks
+
+> Why should we *not* do this? Please consider the impact on teaching Ember,
+on the integration of this feature with other existing and planned features,
+on the impact of the API churn on existing apps, etc.
+
+> There are tradeoffs to choosing any path, please attempt to identify them here.
+
+## Alternatives
+
+> What other designs have been considered? What is the impact of not doing this?
+
+> This section could also include prior art, that is, how other frameworks in the same domain have solved this problem.
+
+## Unresolved questions
+
+> Optional, but suggested for first drafts. What parts of the design are still
+TBD?
