Would you consider renaming this package from blackbox to blackboxwm? This would correspond to the upstream source repository name. https://github.com/bbidulock/blackboxwm It would also free up the blackbox package name for another project using that name. https://gitlab.gnome.org/raggesilver/blackbox Ideally both of these projects can be packaged in Fedora, or even be installed on the same system. Renaming this package is one possible method for achieving that. Other methods could work but I think this one makes the most sense. If you're open to this but just don't have the time, I would be happy to help with the transition.
This is being discussed upstream as well. https://gitlab.gnome.org/raggesilver/marble/-/issues/10
I believe it's better to change raggesilver/blackbox to blackbox-terminal or something like this.
