It doesn't make sense to maintain a list of 'known but ignored devices',
those should just be added as known devices.
It would make sense to be able to see a list of known devices which have
not been seen in a long time, too. Those might have been decommissioned
and therefor be easy targets for cleanup in the database.
For the UI, it does make sense to be able to zoom in on things which are
'recent' or things which are 'old'.
