After some digging in the upstream kernel, I found this commit:
-----------------------------------------------------------------------------
e0361b70175f0cd6199dd9ed6679632de73973d4

    Input: wacom_w8001 - split the touch and pen devices into two devices
    
    These devices have a pen device and a touch device through the same serial
    protocol, split it up into two separate devices like we do for USB Wacom
    tablets too.
    
    Userspace already matches on the device name so we can't drop it
    completely. Compose the same basename based on capabilities and append the
    tool type, leading to a name like "Wacom Serial Penabled 2FG Touchscreen
    Pen".
    
    Note that this drops BTN_TOOL_FINGER, it is not needed once the tools
    are split out (and a touch device with BTN_TOOL_FINGER is interpreted
    as touchpad by most of userspace).
-----------------------------------------------------------------------------

It is the last recent of 5 commits which introduce changes to the W8001
serial driver.

It's just a guess - may be, the new device isn't considered for screen
rotation?

Title:
  Wacom serial: Screen rotation triggers pen/eraser rotation but not for
  finger touch

Status in xf86-input-wacom package in Ubuntu:
  Confirmed

Bug description:
  After updating to xenial the finger touch was broken. With an update
  to yakkety the finger touch device came back, but it doesn't rotate
  with the screen, how it used to in former releases. Pen and eraser are
  rotated as expected.

  I discovered, that the bug occurs only with linux kernels after 4.4,
  so it depends on recent changes in the kernel.

  The 'xsetwacom list devices' command generates the output:
  Wacom Serial Penabled 2FG Touchscreen Pen stylus	id: 15	type: STYLUS    
  Wacom Serial Penabled 2FG Touchscreen Finger touch	id: 16	type: TOUCH     
  Wacom Serial Penabled 2FG Touchscreen Pen eraser	id: 18	type: ERASER    

  ... but with the old linux kernel from utopic (4.2.0) the ids are different:
  15 for the stylus (unchanged), 17 for the eraser, 18 for finger touch

  This bug affects:
  * an updated system how described above
  * a fresh installation of yakkety (used to file this bug)
  * the zesty daily build
