two reasons for me; these apply to any remote administration suite for printing and not just octoprint. 1) It isn't pleasant to be near many industrial machines. Chemical vapor/off-gassing can be a real problem, so on top of the usually loud metal-component motion systems/gantries you have loud evacuation/exhaust fans. One place to deal with webcams/remote features on many machines at once is convenient. 2) Real time notifications create less machine downtime. A thermistor failed so a machine stopped mid-print? This time can be salvaged by a notification to browser or mobile for quick repair rather than discovering the issue by returning to the machine at the supposed end-time and being greeted with a non-finished print.
