Then there's a dependency on the other OS instead, and *it* either has
a dependency on the driver, or is free software and we can just do it
the same way they do. So now you have a dependency on non-free
software, and several ways to fulfill it.
If you could express the entire software dependency tree in free
software, then the software at the root of that tree is also free and
can go in Debian.

Great, so can lspci. Waste of time and archive space. It's a driver,
not a card prober.

Firmware that is optional is, well, optional. Suggests is a perfectly
reasonable expression of that. Depends is not.

No. It's a driver for an ipw 2100; it has an ipw2100 and can't drive
it. It's not functional -- it failed to power on the adapter. In the
case of Windows and Grub, Grub is a generic bootloader. It can
usefully boot Linux, Hurd, or NetBSD without access to an XP
bootsector. It has significant useful functionality. What device can
the ipw2100 driver drive without the firmware?

This certainly doesn't make Debian uninstallable. All the drivers in
question can move to contrib. It just ensures that Debian ships only
free software in Debian main.
