I've tried to use PatteryFly a few times, it's actually a pretty terrible system. the biggest drawback is the lack of documentation...as you click through what they call documentation it's full of missing content and 404's. Personally, it's just better to use adminLTE or Twitter Bootstrap.
With the exception of RHEL, it's just like most of Red Hat's products...purchased from someone else, half-baked, and a rather pathetic attempt to stay relevant. It seems that the only support is from internal RH devs and if you look at a lot of Red Hat's other products, even they can't really figure out how to use it (see ManageIQ).

That's because it's an internal RH framework. Red Hat happens to open source most of their stuff, so they put some effort into marketing PatternFly, but it's still mostly used by themselves.
That being said, the people on their Slack channel are extremely helpful!
