Taking a step back, choosing the sphinx-rtd-theme to begin with was
purely arbitrary, I didn't put much effort into checking the
alternatives, and as far as I recall, neither did Jon. There were more
pressing issues at the time to get the documentation generation ball
rolling at all.

Obviously anyone can change the theme for themselves, and I guess the
question is rather what the default is, and, subsequently, what gets
used at [1].

I haven't followed the development on this closely, but I am somewhat
surprised at the amount of theme overrides having been added, and it
begs the question whether there'd perhaps be a readily available stock
theme that would be better suited than sphinx-rtd-theme?


BR,
Jani.
