Volumetrics should appear in Cryptomatte, Object ID and Material ID

We just wrapped work on a film that used OpenVDB sequences for smoke, fog and lighting. When I went to render, I discovered that volumetrics are not included in Cryptomatte, Object ID or Material ID passes. This makes compositing, post production and VFX production work involving simulation elements problematic.

I reported this as a bug but was told that it's not a bug. It's just how Blender works.

I am therefore proposing that volumetrics be added to render passes so they can be included in Cryptomatte, Object ID and Material ID.
