python2-pyqt5 and python2-pyqtwenengine can also be dropped, but those aren't mine, so I pinged the maintainer.
So, 11 for now.
I thought there would be even more, but apparently python2-feedparser is still needed by some "rawdog" thing???
And soupsieve, beautifulsoup4, html5lib, lxml, cssselect are all in some tangled circular checkdepends situation, with html5lib required by python2-pip. If I could drop those, I could drop pytest-expect and webencodings too...
pillow is still needed by Kodi.
EDIT: also python2-sip-pyqt5 and python2-opengl could be dropped once python2-pyqt5 is removed.
So, 13.
