I would have expected something regarding serialization in the
description of java.lang.Record.

Right now, it appears to be possible to have a record implement
java.io.Serializable, and serialization will appear to work, but
because the names of the implicitly generated private fields are not
specified, it is not portable across compilers and even compiler
versions.
