That would be a rather strong unilateral decision. Why don't you ask the authors? In theory the PEP's proposals could serve in situations where asyncio isn't appropriate, and asyncio's subprocess I/O isn't the smoothest API imaginable. (In practice I'm not sure if the PEP would have been written with asyncio subprocess support in place.)

Hi,

On core-mentorship someone asked about PEP 3145 - Asynchronous I/O for
subprocess.popen. 狢 answered that asyncio now has subprocess support
(including non-blocking I/O on the three standard stream pipes), so
it's not obvious anything else is needed.

Should we change the PEP's status to Rejected or Superseded?

Regards

Antoine.
