AOV Light Path Expressions (Render Passes)

Is it possible in blender 2.8 to create custom AOVs with light selects? For Example: you can give a light group a custom name attribute and have an extra aov layer for that in comp. This would be a huge help for compositing. Something like this:

docs.arnoldrenderer.com/display/A5ARP/Light+Path+Expression+AOVs

rmanwiki.pixar.com/display/REN/Light+Path+Expressions

So I mean not creating another Render Layer.

I know that there are some posts already out there, but they are all really old - so is this on the roadmap for 2.81 or 2.82?

There's a conversation on Devtalk about this. devtalk.blender.org/t/light-path-expressions-for-custom-aovs/9193 It looks like Ubisoft animation Studios is interested in this technology.

Brilliant, I was just about to make a proposal for a per light aov's.

* @3d illusions * Per-Light AOVs are sort of already in the works. 2.8 will have the ability to render light groups, but it's limited to 8 right now. I'm pretty sure LPE is being considered but requires a bit of refactoring.

* @Josephbburg * is this in an experimental branch? Can't see it in the 24th's 2.83 daily build.

I would love to see this implemented. This provides a huge workflow boost for lighting and rendering shots and is a common workflow for studios
