Describe the feature

Right now, useAsyncData uses a ref to store the data. This means that, when returning an object (or an array), the whole object will be made reactive. This can have unwanted performance penalties, depending on the size of the data that is fetched, and depending on the use-case, is often unneeded when returning static data from an API call that is not meant to be changed.
It would be great if you could use a shallowRef instead.
