From my perspective (User+Admin), I'd _very much_ like to have
(physically) removed disks be removed by md.

This would greatly help me when a disk fails on any of my systems.
They are all SPARC's (with a few x86). None of which have any
monitor attached. The x86's have, but that monitor is a couple of
hundred meters away...

So when I change drive, I first have to telnet into the terminal
switch port for that machine, do the mdadm commands. Then physically
change the drive. Then back to a machine and telnet back in to the
machine and hot-add the disk....

Granted, it don't take that much time, but it's a couple of extra
steps (literally :) that I'd prefer not to do/take...
