Default [Q] Nexus 5 4.4.1 camera portable?

4.4.1 dropped for N5 and it came with huge camera improvements including HDR and HDR+ modes. According to the N5 threads the new camera works on CM11 (for us AOSPers) but I tried it and I get FFC reboot and main camera is really laggy. Is it portable? Will this camera update be able to be included in other AOSP roms? Or is it and update specifically for the N5?
