What is pbbuttonsd used for nowadays?

[Stefan Monnier <monnier@iro.umontreal.ca>]

I notice that my Debian testing install includes pbbuttonsd and starst
it at boot.  But looking at the home page of that project, it seems that
what it offers is already provided by other parts of the system nowadays.

So is it still useful, and if so for what?
