+This page gives an overview of our stability guarantees.

+## Exemptions
+
+Even if some of our infrastructure can be used by others, it is still considered
+internal and comes without stability guarantees. This is a non-exhaustive list
+of components without stability guarantees:
+
+* The CLIs and environment variables used by `remote-test-client` / `remote-test-server`
