This can also enable a better discovery (if wanted by the client) of new 
media types that are previously unknown to the client, that tries to 
consume the delivered response. Analogue the HTTP Upgrade header field 
for HTTP version protocol upgrades and the generally of evolvability 
(allow the extension of client functionality).
Furthermore, it nicely aligns then with the good feature of 
decentralization that the Web gave us.
