The simplicity of the commands interface on top of the more functional
subprocess interface, no?  subprocess is very powerful but there isn't
a simple way to get the output.

See http://docs.python.org/lib/node530.html, and see the docs comparing
os.system() with subprocess,


So, if you added 'getstatusoutput' and 'getoutput'-style commands to the
subprocess module, you would

(a) be able to deprecate a module in the stdlib, simplifying it a bit,


(b) provide simple commands implementing a common use case for subprocess,
	"run this command and give me the output".  (You can already
	do 'getstatus' with a 'Popen(cmd).wait()'.)
