I can't help with your actual problem but I am incredibly curious about how/why you run into this so frequently you need a tool for it. I feel like in my 15 or whatever years of using git I have basically never wanted to remove a hunk from an old commit or anything similar.
I try to leave a good commit trail in my PRs. These are often _not_ the reality of how the code was written and originally committed, but a rough approximation of the intended steps with the benefit of hindsight.
A tool like https://github.com/tummychow/git-absorb has been on my to-try list for a while, but for now I do it by hand.
