Please forgive me, when I point to this discussion:

https://forums.unrealengine.com/showthread.php?118457-Custom-lighting-models-(and-usf)-support-in-plugins-needed-Is-Epic-planing-to-improve-plugins

Is there better plugin support coming in the near future? meaning 4.14 - 4.15
Can EPIC please give some hints, if this is roadmapped in near future or dropped into the uncertainty basket?
