Apart from the coordinates telling you where it is on screen, what’s the difference with
the USB and later BLE versions of the PowerMate:
from a user's POV I think that's a rather big difference, same as the
difference between an intuos and a cintiq or the indirect/direct touch

I’d be interested in having one of the Griffin or Surface Dial working, so
we can avoid having to change the plumbing that could get a bit too Dell
Canvas specific. (Surface Dial: 87€, PowerMate 92€)

But do we know whether they’re going to use it? It’s not like you can plop
down about 100€ got the functionality, you also need the huge expensive
tablet to go with it.

Do we have any way to pass down the physical size of the device, when it’s
on the tablet’s screen? Are the MS and Dell devices interchangeable? (I’m
guessing not) If we have infrastructure for those radial menus, will
we/should we start using them for the dials on Wacom tablets?
I can handle this in libinput and pass it down. Fwiw my current way of
thinking is to handle this as another tool in the tablet interface, adding
extra axes to that for width/height is a trivial API addition. I somewhat
rely on the kernel to give me sane data but c'est la vie.
