I don't think that's a viable approach for most use cases: it requires
all applications using any of the Rump drivers to run with full hardware
access. That's like MS DOS -- the exact opposite of a microkernel
architecture :-)

While theoretically there are ways to avoid that (see exokernel), that
would require considerably *more* changes than running Rump instances as
Hurd servers.
