Great - thanks for taking the initiative with that.

However:
  All previous versions of mdadm were unable to remove disconnected or dead
devices from md arrays.

This is not corrrect.  You can removed disconnected devices with:

  mdadm /dev/mdx --fail detached --remove detached

will fail, then remove, all component devices on /dev/mdx which
have been detached from the system.
This has been possible since about 2.6.2.
