It was requested by Peter Hutterer, see:

http://thread.gmane.org/gmane.comp.freedesktop.xorg.devel/7477/focus=7539

 Julien> it seems to me clients can't do much with that information?

I don't personally have a need for this. What I do need is a stable
identifier (which xinput ids aren't) to be able to apply per-device
transformation properties for multihead touchscreen setups - E.G. the
EVIOCGPHYS stuff in the link above.

For the use case of this, see my earlier patch:
