Can the reference of an object be kept when it's put in $state([])?

[ratrakone]

Describe the problem

when i create an object and want to push it to two different arrays, like a flat and 2d array it loses the reference.
or when creating components, where there are items and _items i need to use the last element of the array because it's copied.
i can live with it, because there are workarounds, but with complex data it is easier to get lost.
here's a playground with latter example, try typing in the inputs

Describe the proposed solution

if it is somehow possible to retain the same object reference when putting it in a $state() it would be delightful
