There are concerns about the implementation of Real Time Kernel as expressed in the Musician's Guide:

I am not a systems programmer so I can't speak to these concerns.  Some of the names of the real time kernel developers listed on the PlanetCCRMA kernel-rt page are Red Hat employees.

I would like to see Fedora be the premier linux distribution for music.  But until we can overcome the concerns listed in the Musician's Guide we will probably not have a real time kernel in the Fedora repositories.  Maybe a Fedora "Re-Mix", or Fedora.Next and Workstation with the works with Fedora software library may break the ice.

Well, I think those concerns are why Ubuntu moved to their low-latency kernel instead of their kernel-rt. According to their documentation (wiki) the lowlatency kernel is a "soft" preempt kernel and the rt kernel is "hard' but there's no docs on what make them different, and people in channel don't seem to know. 

Following their lead may resolve some of those concerns, and also may indicate the time to move away from KDE for potential stability reasons.
