@Crell @nielsdos @beberlei No. Looking at the code it's a single-linked list. To insert at the end you need to traverse it in full. Effectively:

$item = $listStart;
while ($item->next !== null) {
$item = $item->next;
}
assert($item->next === null);
$item->next = $newItem;

Reindexing is not a thing for linked lists, because they don't have an index.
