At one point, SELinux being on by default made one of the Red Hat distros a pain. This high-friction first impression cost them some adoptions, when an IT manager did a test install. A "softening guide" might've helped.
IIRC, managers were qualified sales leads who were actively looking to move to a supported Linux platform, but got turned off by the installer&docs out-of-box experience that seemed like it was going to make a lot of extra work for them.
I just meant the "softening guide" might've helped from the perspective of the company who'd like to land those customers. I don't think it's the best way, but at the right moment it might've salvaged some sales.
