So totally synthetic, not real world.

This driver was added in 2006. Can you point to reports of this being
a real problem any time in the last 20 years? Is this a problem worth
fixing because it does actually happen?

Please redirect your effort to drivers which are still in use. Drivers
from the last 5-10 years. Drivers which are worth fixing, and have
Maintainers who cares about the driver. And problems which are likely
to happen in the real world, not an synthetic setting.
