Different patches, no official implementation because future X11 plans were 
abandoned. The XInput 2.0 support that MeeGo and Mer have is a non-standard 
patch that was once submitted to the X.org guys as a proposal for having MT 
work. After a bit of time, it became clear that the protocol was inadequate so 
they started working on 2.1.

It took too long. By the time they had integrated XInput 2.1 into the 
protocol, all interest on furthering X11 had gone away. Therefore, Qt has no 
plans of ever supporting XInput 2, any version thereof

By that, read: none of the current Qt developers and companies backing them. 
If someone else comes along and wants to do that, it's another story.

It works with either the patches or with other systems than X. I'm told the 
Wayland support is good.

Patching either Qt, or X, or both.
