Nice to see ignore-revs getting some love :) I originally wrote it because I wanted to do a mass-refactoring to llvm-project to change its weird naming convention and "it will mess up git blame" was an objection that was raised. Getting ignore-revs landed took many iterations over several months (thanks Barret!) and at the end of it I felt so drained that I didn't have the energy to do the mass refactoring I originally planned. Oh well. Maybe someday.
