Thanks a lot, Markus - a good and very visual example! As far as I see 
your approach would allow extending it to other modes of aggregation: 
-meth=sum,std, etc.
Would be great to have this as optional flag in v.to.rast!

However- shouldn't the current manual mention that this is not the 
behavior? Some users might not go through the examples.
