If you're doing incident response or on-call work, I think it needs to be more synchronous and more accurate. However, chat messages are more natural to me to indicate availability than setting the availability itself. Too many people don't set accurate statuses and it can get changed by the programs own rules, so it's a noisy signal IMO.
