I arrived at a similar conclusion using Magit. I don't have a 
great understanding of Git, so my best guess is that 64c7b57ae72 
somehow skipped over more commits than expected. You can verify 
that the changes corresponding to the missing commits are present 
in the emacs-29 branch but not in master.
