These things add extra complexity throughout the ecosystem, not just for the end user. Most tools written on top of Git have to be aware of the staging area. Git's own developers, when adding new features to it, need to be aware of the staging area. Jujutsu's authors have pointed out that a simpler model (here, and with first-class merge conflicts) helps them move much quicker. There are many weird and exceptional states with Git that just don't occur, so new features are more straightforward to add.
