That would be great to at least take a look. If it starts to look like
a bad idea, then we can re-evaluate and see if it's better to just
return arrays.
The "weighted" version of the aggregate might be interesting... what
would it return exactly? An array of (range, weight) pairs, or an array
of ranges and an array of weights, or a multirange and an array of
weights?

Not excited about that either.
