Ok, but how do you automate/simplify that?

A script with a while loop and some grep,sed commands? A grep on what
exactly? (this kind of precise information seems to be written nowhere in
the manpage of the HOWTOs)

Wouldn't it be much simpler if it could be possible to do something
like the following?
# mdadm --remove-disk /dev/sda
So this command could mark as faulty and remove of the array any
implied partition(s) of the disk to be removed.
Does this currently exist?  If not, would you be willing to integrate a patch
in that sense? It would be much simpler, don't you think?

Same thing for addition...
# mdadm --add-disk /dev/sda
would do the job quite automatically...
