Hi Matthias,

I've been working for a while on reducing the key package set.
https://release.debian.org/key-packages.html


Pillow is a key package which is perfectly fine;
I'm a long-time happy user of this package myself.


Please consider the patch hereunder to avoid transitively
making Sphinx & Sphinx extensions key packages too.


Please note: python3-sphinx-rtd-theme was dropped altogheter
             as it it nowadays replaced by "furo".


Greetings

Alexandre
