Php8.5 *may* deprecate the use of `__wakeup` (it is planned, but not yet implemented, and it is convtroversial). We use it only twice. In the first instance, it just throws an exception to prevent a security exploit. This can be trivially replaced with `__unserialize`. The other instance is merely to initialize a Worksheet instance variable. Converting this use to `__unserialize` is *not* trivial (one of the reasons for the controversy). However, I see no useful purpose for that variable. Since it has no use, there is no real need for `__wakeup`, so we will just remove the routine altogether, and deprecate the variable's getter (there is no setter). A similar instance variable in Spreadsheet also serves no useful purpose, so we will deprecate its getter as well (again no setter).
