As we often see on this list, people tend to be blinded by their own needs and fail to strike the right balance when considering the pros and cons of a change that may help their immediate desire, I think there is a value in discussing it, even if the conclusion turns out that it is not a good idea to change the default. Rather, make that "even if" "especially if"---we would reach a reasonable balance between pros and cons and won't have to repeat the discussion. > I also wondered why empty commits are "discriminated" in such a way. > I first thought that if you rebase branch A onto B but branch A and B > contain commits with the same changes, then these commits would become > new empty commits instead of simply being ignored. But I just checked > this theory and it is now falsified :) If you add an identical patch on each of your two toy example branches and try to rebase one over the other, an early logic that culls the set of commits to replay based on patch ID will remove them so you would not even see "it has become empty". I think you can redo your example by having two consecutive commits on one branch, and then make one commit on the other branch whose effect is those two commits' effect combined. Then rebase the latter on top of the former. "cherry-pick A..B" seems to be aware of this more interesting case and allows you to control the behaviour by having --keep-redundant-commits and --allow-empty as two separate options, but it seems there is no similar provision in "rebase".
