Somewhat related question to above, when I use key I expect that if I have non unique keys amongst the invocations of key at that point in composition, then something will go wrong. However, it seems to work fine. What should I be looking out for there?

Documentation does not seem to mention what happens when key is not unique. Only that it needs to be unique 😄 Maybe it defaults to "positional key" if there are duplicates but that's just a guess.

That's what seems to be happening in my testing, but confirmation would be nice. Especially since this seems to be an intrinsic and I can't find the implementation 😅

It has sth to do with hierarquy as well. Keys must be unique within the same level

I had non unique keys in the same level, but it seemed like they fell back to positional

I dont know if this is technically correct.. but I usually key a bunch of things that depend on a key, e.g. remember blocks that should all reset when the key changes (in contrast to specifying key for each one). Looking at this through that lens, it makes sense, I think? Even if two key blocks are next to each other, their positions will differ and as such make them unique. I dont know if this is true, but thats how I think about them, perhaps you can share a bit more about your usage?
