Research direction

Start by reading the linked bugs.python.org issue 37927 and its four-message discussion. The migration names no source file, test, or entry point, so first clarify the intended instantiation restriction and locate the relevant interpreter-core tests. Done should be defined by an agreed behavior and corresponding regression coverage.
