Feature Request RT/mixed light, Update Specular Reflections OnEnable and OnDemand...crazy idea?

i was specifically asked by a unity person to ask here as a possible feature request, but this IS a dupe thread so maybe the original needs moving or merging or something but....

i have scenes where the camera is static and many lights do not need to interact with any objects, they just provide static lighting. the thing is, baked lighting looks bad, no other way to say it.
since i cant bake the realtime light effect, it would seem cool to be able to just update in on demand, this would help with the framerate?
i assume i'm not missing something that already does that....
