How to get Maya's main window with Python API 2.0?

[g2m.agent]

This code is provided in the manual:

from maya import OpenMayaUI as omui
omui.MQtUtil.mainWindow()    
ptr = omui.MQtUtil.mainWindow()  

but in Python API 2.0, there is no "MQtUtil".

Therefore, my conclusion is that if you want to use Python API2.0, you cannot use PySide2.

Is that right?

I don't know if there's a separate OM2 binding, but you can just use OM1 for this.  Since this is just giving you a pointer to a Qt object, it's fine to use OM1 here even if you also have OM2 code.
