What is mode="array" doing?

I noticed I forgot it on a couple of form.Field with arrays, but everything seems to be working so the question, what is it actually doing?

Ok, I suspected that 😂 The only usage I found is this inside useField, but I don't get it 😅 
  useStore(
    fieldApi.store,
    opts.mode === 'array'
      ? (state) => {
          return [state.meta, Object.keys(state.value as never).length]
        }
      : undefined,
  )
  useStore(
    fieldApi.store,
    opts.mode === 'array'
      ? (state) => {
          return [state.meta, Object.keys(state.value as never).length]
        }
      : undefined,
  )
