True, but not always true.

Currently, critchton has an option per class on what it serializes it will support.
``` ruby
respond_to(:xhtml, :hale_json)
```

Say, I want to support different media-types on a per object request basis, which crichton permits me to do. Say, I, as an engineer, will support one now, given priorities, and the ability of SQA to test my APIs.  I will need to be flexible in what I code I add to my clients.  This stanza basically does not permit me this flexibility.  It doesn't not allow for incremental development.
