We have already some aggregated Insights on the Analytic Data shared: Add-ons | Home Assistant Analytics
But It is not all Data shared (Analytics - Home Assistant).
Some of them left out by now would, I think, really be interesting and enlightning to see. One example that always instantly comes to my mind: Which custom Add-ons + Version are installed? This would e.g. show Demand for Functions not present in Core. It would be further a nice source of inspiration what’s hot 
Others might be interesting markers as well (how many instances are ssl secured?)
A feature to set the Date for viewing the statistics would be really awesome as well. You could easily see how fast ppl update, if a big wave of rollbacks happen.
