As a side note to your blog post unrelated to the current series:

I think the new proposed history for "rebase-by-merging-a-patch-at-a-time" also improves bisectability because you have less long running side branches (as compared to both in traditional rebase and traditional merge), but a finer meshed DAG where it is easier to split the commit range into half its size. When going back one step in history you have more merge nodes where bisect can decide how many commits to chop off of the new range.
