Description
Resolves #8586

unwrap
method simply castsdelegate

this
since the no-op builders have no delegate builders.The PR also includes minor updates to tests to invoke the builders'
unwrap
method and invoke a method on the underlying implementation's builder.Documentation
Doc update included in the PR.
