GNU/Linux is a nebula of many blocks that sometimes compete for the same role, but heavily rely on intercompatibility and adapter layers in order to allow users to choose the one they prefer in each spot (I know this has been less the case with Gnome recently, for example, but the ideal would be to stick to the principle).
Even though the SysV shim layer can be maintained outside of RedHat, their decision is still a spoke in our wheels.
