Replying to the question in subject, I think it would be better in collections as a class.
Having it just as a function doesn't  buy much, because one can do the same with three lines and a defaultdict.

Four lines. You'll need to convert from defaultdict back to a basic dict to avoid mistaken inserts. For some use cases.

However, if this is a class it can support adding new elements, merge the groupeddicts, etc.
