This is just delightful

Since reagent is rendering this, I wonder if you still need a :key on list elements :thinking_face:

You never really need that, right?

You would need it if you are updating large lists, but most of the time you can get by without it 👌

And since in this case you won't get updates it won't matter in terms of performance either

Right, what you said :)
