Right. The idea would be to ship something like this.

Section "InputClass"
    Identifier "Wacom Devices"
    MatchName "Wacom"
    Driver "wacom"
    Option "Type" "stylus"

The drawback is that the hal fdi system has much more powerful
matching syntax. We could add more of that here (e.g., multiple
MatchName entries means any of them can match) if people want to go
this way.
