Tips for transition to Qt6 from PyQt perspective?

Greetings all,

Unless one is using QML or 3D graphics, or regularly integrates Python code
with C++ code, it seems Qt 6 from the perspective of a PyQt developer will
not be especially disruptive.

Nonetheless, are there any tips to share that would help a PyQt5 user ease
the migration to PyQt6? What are some potentially easy-to-miss tasks that
are actually pretty important?

Can we expect what Qt 6 calls "Additional Libraries" to be packaged as
wheels on PyPi, and be widely available in Linux distros?

I'm curious to know if any developers who maintain Qt Widgets applications
are planning to integrate any QML in their applications because of QML
advancements in Qt 6. I've never tried QML because Qt Widgets has done all
I've needed. But I am curious to know if QML might now offer some core
advantages for some graphical components in some circumstances? I was
interested to learn that a key MuseScore developer is a big fan of QML:
