  no, it never was buggy. There are just no bindings. But all we care about are the events. And events are just a struct. If one wants to use them one can.  An example how one can use XInput from an xcb based application without needing the bindings is https://cgit.kde.org/kwin.git/tree/plugins/platforms/x11/standalone/xinputintegration.cpp
