I'm using XFCE, and recently when an apt-get upgrade caused the X server
to use libinput instead of the synaptics driver, I had a very difficult
time getting my touchpad configured correctly, in the end causing me to
move back to the synaptics driver. There are several issues with moving
from synaptics to libinput:

1) The defaults are different. Depending on your touchpad, that might
   make things better or worse. This will cause people to be taken by
   surprise and then they will have to figure out how to configure it with
   the new system.

2) Configuring your touchpad in a desktop environment independent way is
   harder with libinput than with synclient. Although far from perfect, the
   synclient tool is much easier to use than either xinput --set-prop or
   editing the Xorg.conf file.
