The source project of this merge request has been removed.
Pillow is only used by docutils to determine the size of pictures when using
the scale attribute on an image directive when no height and width
attributes are specified.
In my opinion, this is a pretty niche use-case, and doesn't warrant a mandatory dependency. Moreover, docutils also has optional dependencies on Pygments (for syntax highlighting) and recommonmark (for markdown support), and neither are marked as dependencies in the Alpine package.
