Worth mentioning that the vfx/animation industry is using PyQt and PySide for quite some time now [1].

Major third-party applications and libraries like Autodesk Maya, Pixar's Usd etc. make use of it.

My point being, it is not brand new technology just because it is now maintained by the Qt company. In fact I wouldn't be surprised if this industry is part of the reason why it gained official support.

The use in VFX also spawned a shim library called Qt.py that abstracts PySide, Pyside2, PyQt4 and PyQt5 away [2] - with certain limitations. Highly recommended in the transition phase from Qt4 to Qt5, or when you can't control the underlying Qt-Python library.
