It's not that it "sucks", it's that it requires significantly more
resources. In a minimal install, firewalld is by far the largest memory
consumer out-of-the-box, which is very wasteful in the 99.99% of the time
where it isn't doing anything.
And, the python stack is a meaningfully-large portion of the minimal
install. Right now, that's unavoidable because of yum, but in the not-so-far
future dnf may make it possible to remove that. If we're putting in _more_
python-dependent infrastructure code, we'll never get there.
We are already working towards a rewrite in C for firewalld and
firewall-cmd. firewall-config and firewall-applet will be python also in
the future.
