In my case I already tried to contribute to OpenSUSE, but to keep interest I want to be able to daily drive it. But for now there is a significant number of blockers that prevent me from doing this.
First, the unconfigured default state where Root and only him can do privilegied talks. OpenSUSE is the only distro, to my knowledge, to leave Sudo unconfigured. This result in asking for root password for literally any task. And even once Sudo had been properly configured, Polkit rules are so tight you need to type Root password for many thing more user friendly distroes like Fedora and Ubuntu execute without asking for any password.
And the bloat of the packages patterns are horrible. The base install comes with multiple softwares that are either usefull to almost no one, or that do the same thing as other does. Like xterm installed alongside Gnome Terminal by default, or tigervnc and Gnome Connexion.
It is horrible enough for me to have started my own repositories on OBS to be able to remove some of this bloat by building my own preconfigured package and less bloated patters.
