Aggregate function for the property heatmap-color

Hi,

mapbox-gl-js version: 1.10.1

Question

I would like to construct a kind of temperature-like map. I would like to fill the map depending on the value of my dots and not their densities. The closest kind of layer that I can use is the Heatmap... Is there a way to display a heatmap whose color depends on an aggregation of the point's properties composing it instead of their densities?

Something like that : https://github.com/optimisme/javascript-temperatureMap
where dots will be kind of cluster's centers of other points.

Links to related documentation

https://docs.mapbox.com/mapbox-gl-js/style-spec/layers/#heatmap
The doc says : "Defines the color of each pixel based on its density value in a heatmap. Should be an expression that uses ["heatmap-density"] as input."

https://docs.mapbox.com/help/tutorials/make-a-heatmap-with-mapbox-gl-js/
Here, you've constructed the heatmap from the density, Is it possible to construct an expression based on an average of property of the geojson ?

Start with the heatmap layer section of the Mapbox GL JS style specification and the linked heatmap tutorial, then compare their heatmap-density model with aggregation of GeoJSON point properties. Define whether this requires a supported API change or documentation guidance, and consider the work done when the supported behavior and required scope are clearly established.
