Possible to turn off Emissive Material for Lumen GI?

This thread has a custom node that can exclude the emissive from effecting lumen.

Lumen - Material Pass Replace Node

Having played with Lumen and the material editor for a while this morning, it sorely stood out to me that Lumen does not use any of the existing Switch/Replace nodes in the Material Editor, nor does it have its own. Currently, if one would want an emissive surface to be 1 intensity on-screen, but 1000 intensity for Lumen, that’s not possible, while it’d be an incredibly useful control to have for artistic direction.
