For example, all SCADA systems already have command and control alerting for instant degradation response.
Non streaming dashboards are just stupidly hammering the backends (and the network transferring the same data over and over). So this has nothing to do with how cool it looks (also dashboard users rarely complain that they refresh or scroll too fast).
Working on such a backend at the moment, I was missing this feature so much I would probably have started to work on this on my own at some point.
...until I noticed that it transfers the entire chart and all the datapoints each update. (example: https://dash-gallery.plotly.host/dash-live-model-training/)

Problem is complicated when the query applies time series transformations such as moving averages, where requesting only incremental data can be problematic.
