I’m actually wondering if it’s not just applications. That text talks of installing drivers to devices, so I’m actually wondering if this is about better support for hardware that’s paired to specific software. The recent use-case that’s got it on my mind is Rekordbox with Pioneer DJ decks. My housemate was curious so I tried running it under WINE and it launches just fine, but it could not see the decks at all, nor the encrypted license key verification it does with it’s driver. And I did manually install the driver into the prefix first.

However, I’m not positive this is it. It’s just a hunch.
