I'd rather expose isJSONMIMEType.

ok; just so that i understand your suggestion: you want the symmetric use of
isTextMIMEType() and getTextDefaultEncodingName() in NetworkResourcesData to be
replaced by a separate case for JSON + JavaScript MIME types that uses UTF-8 as
its default encoding, and then have another isTextMIMEType() case that uses
ISO-8859-1?
