Because the tablet doesn't report when the tool enters/leaves the proximity.
It just starts/stops sending the coordinates.

A leave timer could be used, though. Maybe we could ignore the case when the
mouse is laying still on the tablet or the pen is held very steadily in
place and just tell that tool left the surface.

Maybe it will be beneficial to have it synthesised after all, as it would
probably ease the integration with xf86-input-wacom and will keep the evdev
protocol more consistent.

Sincerely,
Nick
