Maybe the xserver-xorg-input-synaptics package could hint about this and
point to xserver-xorg-input-libinput? As it is now, I don't understand
how anyone is supposed to figure out that this is an obsolete package;
Package: xserver-xorg-input-synaptics
Version: 1.9.1-1
Installed-Size: 324
Maintainer: Debian X Strike Force <debian-x@lists.debian.org>
Architecture: amd64
Replaces: xorg-driver-synaptics
Provides: xorg-driver-input, xorg-driver-synaptics
Depends: libc6 (>= 2.15), libevdev2 (>= 1.3), libx11-6, libxi6 (>= 2:1.2.0), libxtst6, xorg-input-abi-24, xserver-xorg-core (>= 2:1.18.99.901)
Suggests: gpointing-device-settings, touchfreeze
Conflicts: xorg-driver-synaptics
Breaks: kde-config-touchpad (<< 0.8.1-2~)
Description-en: Synaptics TouchPad driver for X.Org server
This package provides an input driver for the X.Org X server to enable
advanced features of the Synaptics Touchpad including:
.
* Movement with adjustable, non-linear acceleration and speed
* Button events through short touching of the touchpad
* Double-Button events through double short touching of the touchpad
* Dragging through short touching and holding down the finger on the touchpad
* Middle and right button events on the upper and lower corner of the touchpad
* Vertical scrolling (button four and five events) through moving the finger
on the right side of the touchpad
* The up/down button sends button four/five events
* Horizontal scrolling (button six and seven events) through moving the finger
on the lower side of the touchpad
* The multi-buttons send button four/five events, and six/seven events for
horizontal scrolling
* Adjustable finger detection
* Multifinger taps: two finger for middle button and three finger for right
button events. (Needs hardware support. Not all models implement this
feature.)
* Run-time configuration using shared memory. This means you can change
parameter settings without restarting the X server (see synclient(1)).
* It also provides a daemon to disable touchpad while typing at the keyboard
and thus avoid unwanted mouse movements (see syndaemon(1)).

Compare that to the rather sparse description of the replacement:
Package: xserver-xorg-input-libinput

Architecture: amd64

Description-en: X.Org X server -- libinput input driver
This package provides the driver for input devices using libinput library.
It can handle keyboards, mice and touchpads, and essentially replaces the
separate -evdev and -synaptics drivers.
.
This package is built from the X.org xf86-input-libinput driver module.

Exactly which packages does it replace? And "essentially"? Does it
replace them, or not? If so, then why isn't there any "Replaces" field?
But you can't really expect users to look at xserver-xorg-input-libinput
at all. Why should they? There is no pointer to it from the "obsolete"
package. What kind of deprecation is that? Most users will probably
read the first lines of the verbose xserver-xorg-input-synaptics
description, see "enable advanced features of the Synaptics Touchpad",
and think "YES! I want that!".
