Ah I see, thanks for clarifying. These callbacks currently provide a static way to extend the pass pipeline by upstream or downstream driver source code. However, I see this change as a step in the right direction towards having a dynamic way to load passes with something like a FIR/MLIR pass-plugin option that uses these callbacks to do so.
