I'm the author of the BFG, I'll try to help with that. The BFG uses the JGit library to act on Git repository internals - JGit's the library used by Google for hosting the Android codebase, handling thousands of commits a day, and it's basically a pretty serious library. As for the BFG itself, I've used it myself on several critical repositories at the Guardian, and it's been used on many major projects around the world - here's a hundred tweets by different people who've used the BFG: https://twitter.com/rtyley/timelines/464727264345993216 https://twitter.com/rtyley/timelines/464727264345993216 ...and here's a comment by the head maintainer of Git itself, Junio Hamano: https://plus.google.com/+JunioCHamano/posts/Lm7iBwSLvoo https://plus.google.com/+JunioCHamano/posts/Lm7iBwSLvoo So, I guess, most people like it.
