What's missing from these docs is that AMS::Model also serves as executable documentation of the serializable interface, which can be copied or referenced without actually using the class.

Question considering intent of using a UseSerializer with a hash

I think maybe what we want here is something like:
Given a user instance, the serializer should act the user to get the defined attributes and associations. However, since the transformation for a user with id: 1 and name: 'Mortimer' could be compared to something like user_attributes = user.attributes; user_attributes.slice(:id, :name), wouldn't it be nice if we could start from user_attributesas{ id: 1, name: 'Mortimer' }` and have the serializer treat that hash as user_attributes?

Purpose
I found it a bit frustrating sometimes when I just wanted to serialize an object using an AMS serializer, but I first had to define a class for it and either inherit or duck type the needed AMS methods. I showcase how this can be done quickly and dirty but I explicitly say that it is not recommended.

Additional helpful information
Sometimes I felt that POROs (its methods actually that have the same name with the serializer defined attributes) and Hashes (the values which belong to keys which have the same name with the serializer defined attributes) should be serialized automatically without doing anything when specifying a serializer.
