As per my action item of last week, I am gathering all the known issues 
with the sysinfo specification, for further discussion:

* [Issue-79] System information, including sensor data and network 
connections, may permit obtaining sensitive information about the device 
and its user, in particular their location. Access control policies for 
this specification need to be aligned with access to the more sensitive 
information that can be inferred. Furthermore, the principle of 
minimization (the distribution of user data retrieval methods over as 
many interfaces as convenient) should apply as a general design rule for 
this specification.

* Are we being short-sighted in only listing four orientations? Would it 
make sense to have it be an angle, except that in most cases it would 
only change in 90° increments?

* Use focal length instead of maxZoomFactor for cameras? And shutter 
speed/aperture/ISO/sensor type?

* extensibility of enumerated constants, i.e. forwards compatibility 
with new network beyond WIFI, WIRED and PLMN. New constants? Strings?

* checking alignment with /proc filesystem in Linux

* Mapping with DCO (Bryan was tasked to work on that at the f2f)

That's all I can think of for now.
