This is highly technical, but it could be read in a way such that enabling this enables the whole group scheduling dynamic, and the default is that all of it is allocated to root. If that makes sense, disabling group scheduling would make the whole realtime bandwidth available to "the system", and not limited to root, even if realtime processes can still not use the whole system bandwidth. I'm not quite able to wrap my head around the details here, so I'll go for the sysctl solultion (at least for now). Thank you so much Jeremy (and Chris)!
