I'm not quite sure what the issue you're running into is. Can you please send us a hip file?

Thanks for clarifying #1. This would be a sensible future area of investigation for us. We do provide "baked-in" controls for this via the Render Geometry Settings (https://www.sidefx.com/docs/houdini/nodes/lop/rendergeometrysettings.html), but for deferred rendertime evaluation we currently only support what's in the vanilla USD specification.

If you could log an RFE for this, that would be great!

1 - We didn't have plans to add a Karma-specific tab. What would you expect to see there?

2 - That's a good observation and sounds like something for us to address. Can you please log this bug?

3 - This is a USD design thing - https://openusd.org/dev/user_guides/collections_and_patterns.html#configuring-relationship-mode-collections [openusd.org]
