Should also get entries in versions.xml. I implemented this in 8.1 and above.
The backstory here is that people used to have custom serialization methods on these classes, but that broke when someone added the ZEND_ACC_NOT_SERIALIZABLE flag to these classes, making it impossible to serialize even for child classes. So I came up with this trick to unbreak backwards compatibility.

Looks like it broke CI

Yeah, I'm currently debugging what the issue is ^^ I'm also going to fixup the version in versions.xml in the same commit.
