Looking at the code of the sf project and the data you've send me, the
device does not support device properties and only configuration
through sysfs. Controlling such devices will really be a _special_
case with separate functions to write to sysfs from xfconf and
personally I think if the hardware is taken seriously, in the end it
will get a driver with device properties.

I know the wacom and synaptics are special cases too, because of their
property names, but they all use the same code and because of those
names it is easy to detect which device is present. That wouldn't be
the case for the sentelic touchpad and I've read some discussion to
use synaptics for sentelic devices too, so I'm not in favor of adding
this to xfce4-settings.
