The event of new branch "creation" onward should be recorded to the reflog of the newly created branch. As of X days ago, the new branch did not even exist, so that is not a good excuse to copy the reflog.

Also @{-1} comes from the reflog of HEAD, which is different from what we are discussing.

To me, it makes no sense, with these analogies. If I make a copy of a file one month old with timestamp copied, I may appreciate that the newly created copy hasn't yet been touched by looking at the old timestamp, but that does not necessarily mean that I want to pretend that the new file was there from that old date, or I want to pretend that the last time the new file was edited before that was at an even old time.

If I were renaming a branch, that is a totally different story. In the mental model, the "identity" of the branch did not change, only the label that I use to refer to it (called "name") has changed.

But I do not expect copying to split and give half the identity of the original to the new one.
