Export the bound "list" variable, as you have with "container"
Extract the "list-item" markup into it's own component. This means should the user create their own "list" slot, they can use your "list-item" component
Following from point 2, could all functions/actions used by the "list-item" be extracted into their own javascript file so the user can import them should they want to create their own "list-item" via the slot. This is probably quite the rewrite, though.
I probably have others, but I'm only now migrating from v4 and this is what I'm finding so far
