Something similar was discussed before here:
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.samba.org%2Farchive%2Fcifs-protocol%2F2012-June%2F002343.html&data=02%7C01%7Cobaidf%40microsoft.com%7C2aaa70f3b41c45bce0e708d6bc28c627%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636903280648023447&sdata=YXYLWz%2BtKHBqEeVfKdflzGcJMejNTEd9TCr6OzcVGjc%3D&reserved=0
And I'm pretty sure is that constant was present somewhere in the Window Protocols documentation, but I can't find it anymore.
So somethings has changed in the documentation and also the implementation over time.
It was also part of the discussion with Microsoft around CVE-2016-2118, but the Microsoft fixes for that CVE didn't include any change.
So I guess the changes happened after the CVE-2016-2118 changes.
