Talking [Q] [F2FS] Lego Kernel - what happens with Android L?

I have a Nexus 7 2012 Wifi running OmniRom 4.4.2 with the F2FS Lego Kernel which really improved the performance of my tablet that started slowing down after about a year of use.

My question is will the new version of Android (Android L) be compatible with F2FS? Maybe we wont need F2FS anymore since ART will be the default? Just asking to know if I should revert back to a stock kernel and wait for the Android L release.

Thanks!
