it is pity that so cool feature as popularity heatmap is not global
it cover Moscow but not covering my city - Kazan
can we expect you will complete this for everyone but not just for favorite countries?
True, would be good to calculate global HeatMap.
But looks like they just stopped updating it, so I wouldn't expect this soon.
Already existing HeatMap is old, there was thread about it: Outdated OSM on Garmin Connect (Web).
