I do not think tree-to-tree thing is very useful and that is what I meant to say by "tree-to-tree is still stronger than necessary". What is recorded as a "change" by darcs feels more like "This makes it to do Y instead of doing X", and it is not about tree-to-tree. I know David Roundy is lurking on this list; David, do you have any comment on this?
