The RCP2 is replacing VoiceMeeter, a StreamDeck, and a PCPanel Pro.
It's not a problem, I have a few tricks to maintain orientation, and physical devices on a desk are quicker to manipulate than trying to use a desktop utility via a virtual desktop, and moving a mouse with controllers can be inaccurate at best, but I can easily poke a slider or button with a fingertip.
As for visual confirmation, no passthrough required, the lights on the mixer can be peeped down the nose-gap in the face gasket for location, and once you're familiar with the equipment it's not too hard to do exactly what you need to do within a second or two compared to the 20-30 seconds it takes to invoke a virtual desktop and try to drag voicemeeter out from behind OBS and the window you were actually trying to record
