In the variable handler, we just go through the entire thing and keep every element once. If there's a duplicate, we set it again, which calls the handler again. This takes a bit of time, to be paid on each startup. On my system, with 100 already deduplicated elements, that's about 4ms (compared to ~17ms for adding them to $PATH). It's also semantically more complicated - now this variable specifically is deduplicated? Do we just want "unique" variables that can't have duplicates? However: This entirely removes the pathological case of appending to $fish_user_paths in config.fish (which should be an FAQ entry!), and the implementation is quite simple.
