But there is a tradeoff, as mentioned in the package description:
This version of Zenmap has a user restriction due to Flatpak: It can’t be run as a root user. For all but some specific cases this package should offer feature parity, but it’s important to understand that this is trade-off between security and power.
I think Zenmap no longer has Python 2 dependencies. So maybe we should recontinue the dnf package for Zenmap.
