I didn't quite follow that thread far enough to see the conclusion that lead to this direction (rather than improving/modifying bugpoint) - might be worth writing a bit more in the commit description about the conversation (link to the thread if that's helpful) and design choices - and long-term plan (to merge behavior, share things, remove one or the other - or should these two tools exist indefinitely with different goals/uses?)

The intent is to build this separately, then fold it into bugpoint? What's the tradeoff/motivation for that compared to building this into bugpoint to begin with? (seems like it presents a risk that that unification doesn't happen & we're left with a fractured solution ('one more competing standard' sort of situation)) Is the desire to get this reviewed/committed sooner while pursuing some bugpoint refactoring necessary before unification, without delaying implementation of this tool until after that refactoring?
