I'm not sure this really makes sense. It sounds like RedHat didn't hammer it down throats, but instead created a solution that had some guarantees of support and traction which distro maintainers then decided was better than the current alternatives. No one was holding a gun to distro maintainer's heads tell them that they needed to move away from the existing solutions or else, or at least I haven't seen any evidence of that.

So if they weren't forced into it and RedHat did indeed provide some guarantees, it does actually suggest what the parent says.
