That looks like a useful addition, but it still requires someone to
code up the custom configurations and deploy them. The nice thing
about about doing it here is:

1. We can ship the quirks with the driver and not have to rely on any
out of band mechanism

2. It's entirely independent of the desktop stack in use

The mechanisms are independently helpful, though.
