I imagine it could be useful when importing a huge tree in the first commit,
when some data in the tree is redundant with (or similar to) others in the
same tree. I guess there could be some other VCS use-cases.

The real case where I've been using this is that I use git to store my debian
build logs in an efficient manner, and having a custom-sorted list of objects
ends up being much faster and less memory consuming than using a huge
window (and 1GB of logs became less than 10MB).
