No, unfortunately, since as you've noticed the command module makes
assumptions about the use Unix shell syntax. It doesn't look like
this got revisited as part of 2.0, although I agree it might be the
logical place to isolate such dependencies.

Even prior to 2.0, it's not terribly difficult to isolate the OS check
in one place and just bind a name to the appropriate popen. It
doesn't have to be much more than:
import sys
if sys.platform == "win32":
import win32pipe
mypopen = win32pipe.popen
else:
import os
mypopen = os.popen
and then anywhere later that you need to create the pipe, just use
"mypopen". If you've got a large, multi-module system, you could
stick this in some common module to avoid replicating the check.
