If I understand the target of this issue, this is a breaking change in python 
3.9 .

E.g. see https://github.com/SAP/PyHDB/issues/149

Ideally if we did not intend to break libraries then can this be fixed?
Or if it is acceptable to have such a breaking change, can it be documented as 
such? (maybe this is https://github.com/python/cpython/pull/23096 ? though I 
would not interpret that as a breaking change at first glance)

[issue40851] subprocess.Popen: impossible to show console window when shell=True

[akdor1154]

New submission from akdor1154 :

Hi all,
It seems impossible to show a new console window with calling subprocess.Popen 
on windows with shell=True.

Attempt:
si = subprocess.STARTUPINFO()
si.dwFlags = subprocess.STARTF_USESHOWWINDOW
si.wShowWindow = 5
proc = Popen(
cmd, cwd=runFolder, creationflags=subprocess.CREATE_NEW_CONSOLE, 
shell=True,
startupinfo=si
)

In the current source, it looks like this is due to the block in 
https://github.com/python/cpython/blob/master/Lib/subprocess.py#L1405 , which 
unreservedly wipes wShowWindow even if I have provided it.

Testing on Python 3.6 but I am assuming this affects all versions.
