Using slots or render functions to proxy rendering preserving reactivity

[hypeJunction]

I would like to enable a type of composition that would not require passing down props endlessly through slot templates, making it really difficult to achieve type-safety and requiring generics.

So, instead of:

<Table :items="items">
  <template #item="{ item }">
    <b>{item.name}</b>
  </template>
</Table>

I would like to pass a render function:

<Table>
  <template v-for="item in items" :key="item.id">
      <TableItem>
        <b>{item.name}</b>
      </TableItem>
   </template>
<Table>

The problem with the latter however is that if I take the default slot from inside TableItem, push it into some stack inside a ref provided by the Table, and then invoke the slot inside Table template, the content of the rendered items is not reactive.

My expectation was that a reactive change in any of the children would bubble up to the top, but it seems that reactivity is based on props and because the TableItem does not accept any props, nothing ever gets rerendered.
