The context is included every time you call .json(). This makes sense when its a Manifest / Collection / AnnotationPage but it might not be necessary if you are trying to access things like provider or the metadata section as JSON.

The suggestion is to add a optional parameter excludeContext which defaults to False. This would give the option to just get the JSON without the context being added.

Alternative options are to only include the context for the .jsonld method or to only include the context if the object is a Manifest / Collection / AnnotationPage.
