This should make the tablets more useful out of the box.
At least with xf86-input-wacom, I believe today's default mapping
causes an almost direct mapping to X button #'s so that means BTN_0 is
dropped (X buttons start at 1), BTN_1 treated as LEFT and BTN_4/5
treated as BACK/FORWARD (it skips over buttons 4/5/6/7 when creating
default mappings).
So for most people, its only the BTN_LEFT/RIGHT that would cause a
visible difference and I'd think for the better.
I have one question below.

Can you add a message to commit on why this is deleted instead of
changed? I'm guessing WACOM_MO series must support mice pucks and so
already declare BTN_LEFT and BTN_RIGHT?
Other than that:
