I’ve just checked yesterday and updated the Windows Synaptics drivers to the newest version, but the reported firmware version (4) stays unchanged.

Sorry. Are you saying “Oops, thanks for the report, I’ll fix it” or “I’ve just given you three ways to tell libinput my preferred acceleration, so sysfs is going to stay broken for firmware version 0x04”? I doubt that sysfs is “rarely” used and, mind you, not everyone is using GNOME and Wayland. Adding Greg KH since he’s asked for objections in <20170828080530.607134002@linuxfoundation.org>.
