Thoughts on adaptTo returning Optional instead of null

[Shurmer, Jordan]

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:
