>> The `class` file format often only stores lists up to 65535 in size because size is encoded as a u2. Currently, we truncate the list size and write all contents, creating malformed `class` files. Almost all scenarios where such oversized lists are created can be considered an error; we should eagerly reject lists that would never be encodable in the `class` file format when users construct model objects.
