Or asked differently, is > there any supported build host that provides only sphinx-build-3? > Yes, modern Fedora still uses "sphinx-build-3" as the name in /usr/bin for the rpm-packaged version of sphinx. It's just that the only platforms where "sphinx-build" is the 2.x version are platforms on which we want to drop 3.6 support anyway, so it's OK to invert the search priority in the context of this series. (All pip/pypi versions use "sphinx-build" as the binary name. In effect, this patch means we prefer pip/pypi versions if they're in your $PATH.) >
