Grsecurity? Anyone use this?

So, I've been doing some research and seeing that no OS is immune nowadays to external and internal threats, the only solution is SUID and strict compartmentalization of processes and memory usage. Upon doing some research on how best to achieve an optimal state of balancing functionality with security I found a group of dev's and some serious minded security experts releasing a project under the name of grsecurity. They've been operating for over 15 years now and are the gold standard in security for UNIX based systems. I find it incomprehensible that popular distro's don't include this kernel patch by default in their releases. I'm wondering about your thoughts on this and what can be done to raise awareness of utilizing and possibly funding this research group along with implementing it in popular Linux distro's.

Thanks.
