It's best to wait and see.Why do you say that? Port will probably be super easy as the changes are small.
I'll give you an example (taking the official Cyanogenmod support as reference): the Nexus 4 (made by LG for Google) is nothing more than a version/configuration of their own LG Optimus G (with less storage, camera sensor with less MP and 4G disabled), yet the Nexus 4 still has good support (official CM13, maybe upcoming CM14.1) while the Optimus G support died earlier (officially nothing after CM12.1).
Never underestimate the hassle of small caveats or how a small(er) user-base may allow it to be forgotten.
