Thanks for pointing that out. Our starting point for applying the Render Pass has been based off of code in the USD repository for RenderMan. That includes, by design, only applying matte data to *geometry* (https://github.com/sideeffects/HoudiniUsdBridge/blob/houdini21.0/src/houdini/custom/RAY/BRAY_HdKarma/BRAY_HdRenderPassSceneIndex.C#L127).

Your suggestion that we should support specifying this at the parent level is sensible, especially given that we support this when using the Render Geometry Settings LOP to set the matte flag.

Can you please log a bug/RFE for this? I won't be able to focus on this today, and I don't trust myself to remember to come back to this otherwise

Can you send a sample hip that demonstrates the issue in #1? I'm unable to reproduce (based on what I understand it to mean at least).

Thank you for this. Our instancer LOP indeed only explicitly authors invisibility, which is ultimately the issue here. This is not something we'll be able to look at further before the holidays. It would be immensely helpful if you could log this as a bug.
