[GSoC] question for an additional objective

Hi! I'm working on my proposal for 'Complete and extend the remote-object-info command for git cat-file'

While thinking about what else I could suggest to contribute to the project, I had an idea I would like to get feedback on: In a partial clone, someone might want to know what blobs are missing inside a concrete tree and their size before fetching them.

The idea is to build on top of 'remote-object-info': given a tree hash, return the missing blobs (inside that tree) ordered by size.

Is this too ambitious to be on the same project or even a good idea?

Thanks, Pablo.
