IMO whenever you're tempted to do calculations or extensive grouping 
within your template, you should think about an intermediate model that 
encapsulates that aggregate functionality.
E.g. if you think about a shop: you wouldn't want to iterate through the 
articles and calculate the total in your view. Instead you might create 
a "Basket" model that contains the articles and can do those 
calculations for you.

The same here: Just create an object that matches your domain and assign 
*that* to your view. Even if the domain in your case is very flexible, 
it's the better approach in my opinion.

Sometimes it's probably still the faster or pragmatic way to do some 
calculations in the template.. But in that case you're free to install 
the incubator extension or provide the needed view helpers with your 
extension. don't you think?

Best,
