Autocomplete AOV names in the AOV output node
Unique naming and adding .001 does not work correctly in all cases
Add vector AOV output type
View layer level material or shader node group that can be set to output AOVs for all objects
Viewport display of custom shader AOVs
OSL support
Add filtering options (mainly to use either transparency or not, min, max, ..)

OSL support for AOV output, currently I am seeing the shader isn't compiling under OSL while debugging like it is in SVM.

eg. OSL-version (I think) of https://developer.blender.org/diffusion/B/browse/master/intern/cycles/render/svm.cpp$554

Cheers

@brecht there is a patch to add AOVs to EEVEE. It also moves the AOV passes to DNA. In functionality it improves some of the issues as described here, but needs a different interface to external renderpasses so the double naming check works when defining AOVs and when rendering. Perhaps something to look at.

A custom AOV to hold an override material could be good. For when you want an AOV that includes the whole scene (like with a custom depth AOV)

In the original proposed implementation of shader AOVs, support was added for baking AOVs, but was removed in a revision, with the suggestion that it could be rebased back later: https://developer.blender.org/D4837#148553

Is this still planned? I was thinking of trying to implement such a feature myself until I realized it was already part of the old revisions. It'd be really useful for baking maps that Blender's shader model doesn't support without having to piggyback off e.g. Emission.

Any chance to see this implemented for OSL? //
Its` a pitty it is not possible to use it with full OSL glory :(

A way to specify filter (eg. wanting to render some mapping like position reference or a custom UV map from an attribute, and have no filtering applied)

That would be awesome!
