As it stands, yes, so maybe use something like 'status+5d'.

To achieve this with our old BB system with TheState, we had an 'expire'
time included in the status message. A separate process then ran every 5
mins or so and looked for 'expired' statuses and deleted them. This then
allowed a 'default' status to be shown (usually green). (Sorry probably
didn't describe that too well, it is a tad complex but has worked well.)
