multiband raster burning (braindump)

With a "datacube" use case in mind I've been thinking to use a raster to incrementally aggregate values onto its bands.
For that to be effective I was thinking that the concept of "geomval" wouldn't be enough in that for each geometry I'd have multiple values (one for each field to be aggregated).
This ticket is to think about a way to burn a geometry to multiple bands at once.
Note that for my use case there would also need to possibly be a different operations for different bands. A simple example is I want a count of hits and a sum of values (two bands). That way I can compute the average in a second stage, when I'm done burning all records.
