You can do that right now; I expect Ubuntu will, since their userspace
already looks like that. You just need to set $(INSTALL_FW_PATH) when
you install the firmware (or modules).

The Ubuntu folks have chosen not to share their changes with upstream,
though -- and if we were to _impose_ that policy, then we would be
requiring changes to userspace which are not yet widespread. That's a
bad idea. What we're doing right now is _entirely_ compatible with what
userspace already has to deal with for modern drivers, and that's very
important.

There may be some merit in Ubuntu's policy, but we need userspace to
change first, long before we can change the default in the kernel.

But certainly the kernel _allows_ that, if you want it.
