I've been trying to push developers to use Arcanist and, furthermore, for `arc land` to be the accepted way to merge code (currently, we usually do `git merge --no-ff`). One of the concerns that people have with Arcanist is that it is perhaps a little //too// magical perhaps? `--trace` helps to see what is happening under-the-hood but can be very verbose. Perhaps a `--dry-run` mode would help?
