 ## Support for Legacy Platforms
 
-`ImmutableData-Legacy` is a subset of the functionality in our original `ImmutableData` project. To support legacy platforms, we made some changes. Some of these changes — like migrating from `Observable` to `Combine` when notifying components that Selector Outputs have changed — are implementation details that should not affect how product engineers build components. The biggest change to our *interface* — the `public` API that product engineers need — is that Selectors only accept single Dependency Selectors. We do not support variadic types and parameter packs in this version of our infra.
