+# Deprecating Ember Proxies
+
+## Summary
+
+Now that Native Proxy is available in all supported environments, we can deprecate
+Ember's custom Proxy handling provided by `ArrayProxy`, `ObjectProxy`, and `PromiseProxyMixin`.
+
+## Motivation
+
+These patterns were introduce to Ember prior to the availability of Native Proxy. Since
+Native Proxy is now available in all supported environments, we can deprecate these
+patterns in favor of the native Proxy API.
+
+Additionally, we would like to deprecate Mixins in the future necessitating that we first
+deprecate `PromiseProxyMixin`.
+
+## Transition Path
+
+There is no direct migration path for these. Code that relies upon this behavior will have to be rewritten.
+
+## Exploration
+
+To validate this deprecation, I've tried removing the assocaited functionality in this PR:
+https://github.com/emberjs/ember.js/pull/20918
+
+## How We Teach This
+
+We should remove references to these patterns from the guides.
+
+## Drawbacks
+
+By not providing a direct replacement some users may have difficulty migrating.
+
+## Alternatives
+
+None
+
+## Unresolved questions
+
+None
