Please consider keeping the package updated going forward.

While sync is certainly a useful feature, it's entirely possible to use Chromium without ever enabling it; some people might even consider the removal of this Google-specific functionality an improvement.

Firefox is a very valid alternative, and what I personally use, but the fact that the two browsers use different engines makes it quite valuable to have both in the distribution.

Installing the update dragged in the expected dependencies:

$ sudo dnf install https://kojipkgs.fedoraproject.org/packages/python-flake8/3.7.7/6.el8/noarch/python3-flake8-3.7.7-6.el8.noarch.rpm
