В прошлом посте говоря "Все вызовы теперь одинаковы" я несколько слукавил. Всё-таки есть в этом зоопарке версий некоторая несовместимость вызов которой просто так не унифицировать. Эти моменты вынесены в отдельный модуль QtCompat (compatibility). Там не так много функций но они довольно полезны.
Этот модуль содержит унификаци модуля shiboken2, функций loadUi, translate и несколько переименованных функций классов или изменённую сигнатуру аргументов и возвращаемых значений. Это единственное исключение из правила когда вам потребуется где-то изменить свой код кроме импортов и этот код не похож на обычный код PySide2.
Например, в PyQt4 и PySide есть метод
QHeaderView.setResizeMode
Для PyQt5 и PySide2 они были благополучно переименованы в
QHeaderView.setSectionResizeMode
Чтобы применить этот метод следует использовать такой код
from Qt import QtCompath
header = self.horizontalHeader()
QtCompat.QHeaderView.setSectionResizeMode(header, QtWidgets.QHeaderView.Fixed)
Унификация загрузки UI файлов:
# PySide2
from PySide2.QtUiTools import QUiLoader
loader = QUiLoader()
widget = loader.load(ui_file)
# PyQt5
from PyQt5 import uic
widget = uic.loadUi(ui_file)
# Qt.py
from Qt import QtCompat
widget = QtCompat.loadUi(ui_file)
Хорошо что таких моментов не много и их легко запомнить.
Полный список можно посмотреть в таблице.

🌎 The accidental invention of Velcro came after Swiss engineer George de Mestral examined burrs stuck to his dog in 1941. He found their hooks could inspire a new fastening system. Velcro's tiny hooks and loops mimic burrs’ natural grip, and it is now widely used in clothing, space suits, and shoes. ✨

🌎 Before the invention of the printing press, books had to be copied by hand, a process taking months or even years per copy. In 1440, Johannes Gutenberg developed the first movable type printing press in Germany, revolutionizing the spread of knowledge. The first major book he printed was the Gutenberg Bible, completed around 1455 and containing 1,282 pages. ✨

🌎 The MRI (Magnetic Resonance Imaging) machine was invented in the 1970s by Raymond Damadian, Paul Lauterbur, and Peter Mansfield. MRI uses strong magnets and radio waves to produce detailed images of organs and tissues inside the body, without using X-rays. The first full-body MRI scan was completed in 1977. ✨
