Thoughts on adaptTo returning Optional instead of null

Hello Sling Devs,

Currently the SlingAdaptable api specifies that null will be returned if the resource cannot be adapted. What are everyone's thoughts some future version of the API returning an Optional<AdapterType> instead?
For reference: http://www.oracle.com/technetwork/articles/java/java8-optional-2175753.html

Thanks,
Jordan Shurmer

We already had a lengthy discussion about adaptTo() in http://apache-sling.73963.n3.nabble.com/adaptTo-and-results-tt4035466.html.
In case there is ever a refactoring on the adaptTo method the exception handling must for sure be clarified.
