Aha!  This is due to this code:

  /* If purifying, and string starts with \ newline,
     return zero instead.  This is for doc strings
     that we are really going to find in etc/DOC.nn.nn.  */
  if (!NILP (Vpurify_flag) && NILP (Vdoc_file_name) && cancel)
    {
      unbind_to (count, Qnil);
      return make_fixnum (0);
    }

Which will be removed after bug#53024 is done.

But the fixes I did to loaddefs-gen in this bug report fixed this bug
report, so I'm closing it.
