Yes, or magit-blame, but if you still have multiple commits in your history that you are working on, and you need to break up the current changes in a bunch of instant fixups, figuring out which one is the right one can be a bit time consuming. I'm not convinced that automatically amending to the last commit that touched that line is safe, but I'm willing to try git-absorb.

It is not, but git absorb only produces fixup commits, you can still change what they change in the autosquash step.
