• For example, scheduled downtimes with automatic email reminders triggered
• MQTT QoS (e.g., QoS=2 on the Python side so that it keeps retrying, except that QoS=2 has had some recursion issues when too many requests get sent)

The main goal is to have as little interruption to users' workflows as possible.

An important, related concept is over-the-air (OTA) updates, i.e., updating the device without having physical access to it (kind of like a smartphone update).
