Sophos Central - Deleting Devices
Have a double check before deleting a device, not being able to delete a device if Tamper Protection is enabled and having a recycle bin for a deleted devices.
I would agree with Andrews comments - be able to move them to a container where they keep thier history but dont consume a license or get reported on unless they appear again with option to sepcify how long they kept before delted completely.

I would also like to see this but to expand a little on this idea. If a device hasn't talked to Central for a defined period of time (period should be user configurable to suit each organisation) or believed to be dead. You should be able to move this device somewhere (recycle bin) so that it doesn't take up a license (therefore the updates stop) and doesn't get reported on (skews your reports). Should the device ever start talking again in the future it should then move back into Central as a live device once more. If say after a year it still hasn't talked in it could then be automatically purged at that point.
