> makes the numbers more representative of _active_ VR users rather than just users who _have_ a headset but don't often use it

YMMV. My Vive-equipped PC launches Steam on boot, because that lets it install updates quietly in the background as they come in. Otherwise, the first thing likely to happen when I try to launch something is a long wait for stuff to download.

The Vive on the other hand is only plugged in when I actually use it. It gets hot, and I don't particularly want it to burn electricity for no better purpose than to die a premature death.

So even as an active VR user, my Vive is only visible to Steam for a minor fraction of the time my PC is logged on.
