It's a little surprising to hear, from what I've seen here there's not much besides the usual whiff of academical loftiness, but nothing that I'd qualify as aggression.

What caught my interest:

* Separate operations and data

* Partial repos = no big repo issues, no need for shallow clones and such

* Proper and easy merging with no shuffled lines

* Patch-based model is much more intuitive (e.g. rebase and merge are the same operation)

* Conflict resolutions are stored and can be reapplied!
