You still get some of the benefits for the connection to the client, assuming your use case fits. Many typical small setups serve static resources through the "proxy" (i.e. nginx for static assets and distributing requests to backends), benefiting there almost automatically. Similarly CDNs, which nowadays are used even by tiny projects.

(also, if you want your concerns to be taken seriously, I'd tone it down a bit. "so called benefits", "Google HTTP", and "probably coming next year" when QUIC has been in development and testing for over 5 years all don't really give the impression you actually care about the details)
