* Return the enqueued value for a given attribute, if one exists.
*
* Enqueued updates can take different data types:
* - If an update is enqueued and is boolean, the return will be `true`
* - If an update is otherwise enqueued, the return will be the string value of that update.
* - If an attribute is enqueued to be removed, the return will be `null` to indicate that.
* - If no updates are enqueued, the return will be `false` to differentiate from "removed."
