Another question is, can you use multiple components for one "slot"? It would make *some* sense - we need the zombie pigmen to not react to lava, yet to have a very specific reaction to being hit by a player.

The only disadvantage is that all these combinations need to be defined compile-time, rather than combine various components in runtime.

We should make a mindmap of all these thoughts so that we don't get lost
