Yeah, sure! With those changes it work fine here too.
So, feel free to apply the changes.

It sounds that Fedora 30 is conservative with regards to python :-)
The Sphinx version detection script takes it into account,
suggesting pip3 instead of pip - or when called like:
$ ./scripts/sphinx-pre-install --no-virtualenv
Detected OS: Fedora release 30 (Thirty).
ERROR: please install "python-sphinx", otherwise, build won't work.
Warning: better to also install "sphinx_rtd_theme".
You should run:
sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme
It seeks for the python3 packages on Fedora.

Mauro
