I'm not convinced. How do I find out which sphinx-build this
is actually going to use ? ("python3 -m sphinx" doesn't list a
path to anything.)

How do I use the system python but a venv sphinx-build? At the
moment I can easily do that with
because scripts inside a venv have #! lines that make them
work without having to manually activate the venv. I don't
want to have to use some random non-system Python just
because I have a newer Sphinx.

Put another way, I don't think the fact that sphinx-build
happens to be implemented in Python means that we should
let the user's decision about which Python they want us to
use control which version of sphinx-build we should use.
