It seems to me the lesser of the two evils is rebase, but I have not used bisect much. I would think we pick rebase and see how it goes as I know merging can be a bit of a problem. We can always pick merge later if we find a specific issue we need to fix or bisect. I know it is not ideal, but we need to pick one and move on.

What Emacs does everything for you even writes your code for you, that is why I use vim and visual studio code to write my programs just so I feel useful and not replaced by Emacs :-)
