When Plan9 was designed, microkernels were "fashionable". If one reads carefully the paper, it's clear that there is a pun intended against microkernels that didn't achieve what they were supposed to do---disastrous efficiency leading to the rewrite of the microkernels as assembly---a very low signal/noise ratio. And a hint: "micro" kernels are usually _huge_, a clear sign that something went wrong. As drivers are concerned, there was once a kit supposed to give a wide range of kernels, drivers code---I don't know where it is now; I suppose it has vanished. And now probably UEFI drivers is a "better than nothing" solution.
