I'm not yet sure how to allow user to reset props inside GLOBAL_UNIQUE_STORE.

I'm also unsure why it is a key-value store, where the values are equals to their key 🤔
I assume I oversee something.

Don't think too much.
Either move it inside the unique class (effectively removing it global state) or leave it there until we can remove it in v7.
